Milk -Non-Milk Processing Plants Machinery

 How to manufacture  Other Plant-Based Milk - Non-Milk Processing

Different milk / vegan alternatives to milk are plant extracts and their extracts from water. There are many different types of milk made from nuts, seeds, grains, and vegetables. Although the final product is used by consumers in the same way, the processes of milk production based on different crops vary depending on the raw materials used. This application report will manage the following smart processes:

  • Nut Milk

  • Pure Milk

  • Milk Seeds

  • Coconut milk

  • Grain Milk




The process

Peanut Milk:

Peanut milk is usually made from almonds, cashews, hazelnuts, or macadamia nuts. These drinks can be made from whole grains, groundnuts, or powdered peanuts (or flour). When the attachment is used, it should be smooth to ensure that the mouth sounds properly in the final product. Peeled nuts can be roasted to enhance the flavor, or they can be cooked to a blend. The final product is usually filtered through a fine filter to remove any large particles. (Note: Cashews and macadamia nuts are the only nuts or seeds that can be used to make milk without filtration). Stabilizers and stabilizing agents such as locust gum, gellan gum, acacia gum, and carrageenan can be used to improve oral hygiene and extend shelf life. Mineral or vitamin powders may be added to the fortified product.


Legume Milk:

Soya milk is the most popular legume-based milk. Pea milk is the latest in the market and is based on yellow field peas. Soy milk can be made from whole soybeans (soaked in water and ground) or powdered (whole soy flour, soy protein isolate, soy protein concentrate, or dried soy powder). Stabilizers and stabilizing agents such as locust gum, gellan gum, acacia gum, and carrageenan can be used to improve oral hygiene and extend shelf life. Mineral or vitamin powders may be added to the fortified product.


Seed milk:

Non-dairy alternatives to milk may also be based on seeds, in general, sunflower seeds or hemp seeds. All seeds are immersed in water before digesting water. The final product is usually filtered through a fine filter to remove any large particles. Stabilizers and stabilizing agents such as locust gum, gellan gum, acacia gum, and carrageenan can be used to improve oral hygiene and extend shelf life. Mineral or vitamin powders may be added to the fortified product.


Coconut milk:

Pure coconut milk is often sold in tins and used in cooking, while coconut milk drinks are often processed and sold in inboxes. Coconut milk is extracted from the skin of removed coconut skin. Meat is mechanically ground, mixed with water, and pressed into milk, which is then filtered to remove impurities. Although coconut milk contains natural emulsifiers, the product tends to split while keeping the fat-rich cream floating on top. Additional solvents such as guar gum may be added to prevent this. In areas where fresh coconut is rarely available, condensed coconut milk can be made from concentrated or powdered coconut milk, or coconut water (clear liquid found inside the coconut shell). Coconut milk drinks can include other ingredients such as rice or soy. They usually contain compounds such as pectin or locust gum and are often fortified with vitamins and minerals, to complement the nutritional profile of cow's milk.


Grain Milk:

The most common cereal milk is oat and rice milk. Barley, spelling, and buckwheat are also used to make other plant-based alternatives to milk.


Oat milk

Oat milk is produced by immersion and mixing oats with water. Oil can be added to improve oral hygiene and improve the quality of healthy food. The final product is usually filtered through a fine filter to remove any large particles. Stabilizers and stabilizing agents such as locust gum, gellan gum, acacia gum, and carrageenan can be used to improve oral hygiene and extend shelf life. Mineral or vitamin powders may be added to the fortified product.


Rice Milk

Industrially, rice milk is usually made by mixing rice syrup with water and then thickening it with rice flour and starch.


The problem

Peanut Milk:

  • When produced by adhesive, solids can remain in storage, making it difficult to transfer the full quantity to buckets / IBCs. Unripe items may be damaged as a result.

  • When whole-grain production, more pieces of machinery are often needed to grind, disperse and reduce the size of the nut particles in the final product.

  • Particle size cannot be reduced sufficiently and a large amount of raw material may be filtered, resulting in high levels of waste.

  • Oil separation may occur in the final product in the event of insufficient mixing.

  • Grinding machines may not be suitable for firming and tightening (if used).

  • Grinding machines are often unclean and may be difficult to clean.

Legume Milk:

  • Soy flour and protein powders/isolate may have a larger particle size than is acceptable in the final product. A simple disintegration of immature powder may not be enough.

  • Materials used to disperse flour and proteins may not be suitable for added ingredients as thickening agents.

  • Oil separation may occur in the final product in the event of insufficient mixing.

Seed milk:

  • Particle size cannot be reduced sufficiently and large amounts of raw material may be filtered, resulting in high levels of waste.

  • Oil separation may occur in the final product in the event of insufficient mixing.

  • Grinding machines may not be suitable for firming and tightening (if used).

  • Grinding machines are often unclean and may be difficult to clean.

  • If the thickening agents are not completely dispersed, agglomerates may be filtered leading to further damage to the raw material.

Coconut milk:

  • Powdered coconut may have a larger particle size than is acceptable in the final product. A simple disintegration of immature powder may not be enough.

  • If particle size can be reduced to acceptable levels, the raw material may be filtered, resulting in higher levels of damage.

  • Materials used to disperse powders may not be suitable for adding additional ingredients as thickening agents.

  • Simple agitators may not be able to produce stable emulsions.

  • If the thickening agents are not completely dispersed, agglomerates may be filtered leading to further damage to the raw material.

Grain Milk:

Oat milk

  • Oats should be milled as much as possible to reduce the amount of waste produced (this residue can be used as animal feed).

  • Materials used for grinding may not be suitable for creating emulsions.

  • Grinders may not be able to dissolve gums and gums.

  • Grinding machines are often unclean and may be difficult to clean.

Rice Milk

  • The stable emulsion is not easily synthesized using conventional agitators.

  • In some cases, the solution should be stirred longer to ensure that the gums are completely hydrated.




Solution

The Wahal Engineer mixer can be used throughout the entire process of producing non-dairy milk to solve the problems described above.

Stage 1

High-speed rotation of the rotor blades inside the precision mixing head using strong suction, drawing liquid and solids at the top from the bottom of the vessel to the center of the work surface.

Stage 2

Centrifugal force then drives objects into the work area around the head when they are under the action of grinding in a clear mechanized area between the ends of the rotor blades and the inner wall of the stator.

Stage 3

This is followed by a strong hydraulic shear as the material is forced, at high speed, through holes in the stator and distributed to the main body of the mixture. The extruded objects are shown radially at high speeds to the sides of the mixing vessel. At the same time, new substances are constantly being extracted from the operating head that maintains the mixing cycle.

Preparation of Samples for Aflatoxin Testing

Preparation of Samples for Aflatoxin Testing

 Aflatoxin toxins are produced by various types of fungi that can grow in foods such as pistachio nuts, nuts, grains, dried fruits, etc. More information in this article can be used to test other mycotoxins and ochratoxins.

 



Permitted levels of this toxin are very low - usually 5 ppb or less. Analysis was performed to ensure that these restrictions were not violated, and the sampling and testing process is regulated by law in most countries. However, test correction has not been combined with any standard method.

 

A study conducted by the authorities has found that the preparation of samples by scurrying offers significant benefits in addition to drying.

 

 Wahal Engineers high shear mixer blends have been used in this study, and it has been found that the aflatoxin content of repeated samples prepared by scurrying was significantly similar to those prepared by dry grinding. Wahal Engineer compounds are now used as a standard method in several countries.


The process

As mentioned above, in the absence of a standard procedure, there are many variations in the effectiveness of the preparation (or extraction) process, depending on the method and type of equipment used.
The volumes used for sample preparation will also vary depending on the product being tested. 
65 - 90 lbs samples are rare.


The usual procedure would be as follows:


The problem

Sample preparation is subject to several issues:

Effective reduction of particle size and sample homogenization before extraction is essential for accurate and repetitive results.

Other methods of dispersing solid objects, especially on a small scale in the laboratory are difficult to verify and can lead to discrepancies between clusters.

Milling machines may be difficult to clean, exacerbating potential pollution/hygiene issues.

The output phase is subject to a lot of variabilities due to the methods used, as described in the previous diagram. Once again it is difficult to confirm.

Dry digestion can cause severe heat loss.

The viscosity varies greatly from liquid to liquid.

Solution

Experiments have found that the preparation of samples by brushing using tools such as the Wahal Engineer high shear mixer offers significant advantages over dry grinding:

  • Very low CV (coefficient of variation) is available.

  • The particle size can be reached.

  • Better homogenization of samples.

  • Consistent effects throughout the viscosity range.

  • Items of various sizes can be processed.

 

This efficiency and consistency between clusters are based on

Wahal Engineer's head mixing function, which works with the principle of the rotor-stator as follows:


Stage 1 Rotating a large rotary speed inside the working head creates a strong absorption of fluid and firms up

to the working head. Stage 2 The Centrifugal force drives the material toward the surrounding surface of the work surface where

they are under the grinding action where it is allowed between the tips of the rotor blades and the

inner wall of the stator. Stage 3 The solids are extracted by the stator and produced back in the body of the mixture. With a short

cycle of mixing all the contents of the vessel beyond the subject matter, it gradually reduces the

particle size to form a perfectly consistent product.

 

Benefits

  • Reduced cleaning requirements.

  • Processing times are greatly reduced.

  • Laboratory units allow for accurate prediction of the performance of large units when enlarged.

Bottom Drive high shear mixer

 Bottom Drive high shear mixer

Wahal Engineers manufactured Bottom drive high shear mixer are designed in a manner to fit into the bottom or side of a mixing vessel. They are used to disperse immiscible liquids, and for the preparation of homogeneous slurries by mixing chips, powder and breaking of larger size polymer particles. These high shear mixers are typically used in conjunction with a slow speed stirrer or scraper unit for high viscosity products. All the larger particles are crushed to reduce their size into an optimal ratio to obtain the desired slurry. Its major application is for emulsification, blending, dissolution of solids into the liquids as desired by the application. They are also designed for the efficient and homogenous wet granulation of powders to form a medium to high density granule. The working head, i.e., the rotor/stator breaks down hard solids into fine particles. This type of mixer is ideal for high viscosity cosmetic, pharmaceutical and food products. Wahal Engineer’s bottom drive mixers is comprehensively used for a wide range of services, which includes product and process development, process scale up, calibration, maintenance program and pro active project management.




Working Principle:

  1. The major working principle is the shear force produced between the high speed rotations of the rotor blades which exert a powerful suction. This suction draws the solid and liquid material into the centre of the stator head.

  2. The centrifugal force produced then pumps the material out from the rotor head centrifugally towards the stator walls. Here they are milled between the clearance of the rotor and the stator.

  3. Due to the minimum tolerance between the rotor and stator material is crushed subjected to the intense shear force produced and homogeneous product comes out forcefully from the stator. The crushed materials are projected radially outward towards the sides of the mixing vessel. Fresh material is further simultaneously drawn into the workhead to maintain the mixing cycle.

  4. Since it’s a batch process the turbulence created in the mixing vessel disperses a homogenous mixture as an end product.



The system works on the basic Features:

  •  Mixing, homogenization & emulsification.

  •  Dissolving powder ingredient in liquid feed.

  • Particle size reduction with uniform dispersion.
