feed mixers

Feed mixers are used in feed mills for the mixing of feed ingredients and premixes. The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. If feed is not mixed properly, ingredients and nutrients will not be properly distributed when it comes time to extrude and pelletize the feed or if the feed is to be used as mash. This means that not only would the feed not have nutritional benefit, it would be bad for the animals/fish/shrimp that are eating it.

There are a number of different type of mixers used in the feed industry with the most widely used being:

• Vertical Mixer – Used in small farms, they consist of a vertical screw which takes material to the top where it falls back down again, and repeats that process to mix materials
• 
  
• Horizontal Mixer – Consisting of paddles or blades attached to a horizontal rotor, these mixers usually have a higher consistent homogeneity and short mixing times.
• For the horizontal mixer, we have single shaft double screw mixer and double shaft paddle mixer for your choice.

Roasted Soybean Seed

Roasted Soybean Seed - is a good source of protein and fat for poultry. Soybean seed contains a trypsin inhibitor that can severely interfere with digestion in a bird's gut and the seed must be heat treated to inactivate this compound. Roasting is a fairly common method of heat treating seed and roasted soybean seed has been used successfully in organic diets. The processing cost to produce roasted soybean seed is lower than for soybean meal. Roasted soybean seed is sometimes referred as being "full-fat" because the oil has not been extracted from the seed. Because of the high unsaturated fat content of the seed, feeding 20% or more soybean seed may produce a slight fishy taste in the poultry meat or eggs.

Why should you roast Soybeans?

It is important that soya beans are properly heat treated before it is fed to animals. The reason for this is that raw soybeans contain an enzyme that is detrimental to digestion of protein.

Heat treatment also increases the amount of soy protein escaping microbial degradation in the rumen. This reduction of protein degradation occurs because of the Maillard type reactions between sugar aldehyde groups and free amino groups.”

The form of “Full-fat Soybeans” that Roastech’s roasters produce is optimal for milk production when broken in halves and quarters. Fine grinding of beans causes oil release in the rumen, upsetting bacteria and decreasing fiber digestion. Fine grinding of soybeans in the summer also cause rancidity in the beans and also when added to ensiled forages or wet byproducts during warm months leading to animals refusing intake.

In practical terms, what does this mean?

Dry heat from the roasting destroys toxin enzymes in raw soya which interfere with digestion and growth in all animals.

The soluble protein is decreased and the by-pass protein in increased
The protein degradability is slowed down so that more is utilized in the small intestine, known as by-pass protein.
High levels of by-pass protein are a very important ingredient to supplement soluble protein when feeding high levels of lucern or legume hay.
Roasted soya is high in Lysine, an important amino acid which is very tasty.
Retaining the 20% oil in the soybean during roasting is very important because it is a tremendous source of energy which provides 2.25% more energy than carbohydrates.
By roasting the soybeans, the oil is converted into a more digestible form.
Full-fat soya is thus an economical way to provide energy dense rations without increasing carbohydrates in the rumen – thus eat less with more value
Energy packed rations will increase butter-fat from 2 to 6 tenths of 1%
Milk production will increase 3-5#/hd/day
It helps maintain body weight on cows
It provides a prolonged peak milk production
Better breeding results from better feeding
The oil provides a slicker hair coat which improves overall herd appearance
Soy Lecithin remain which increases the speed of emulsification, stabilizes vitamins, is a natural source of choline and inositol.
Soy is a good source of phosphorus and has antioxidant properties to deter rancidity
Properly roasted Soya contains more ruminal un-degradable protein (bypass protein) and the urease and trypsin inhibitors are destroyed. If this is not done, the trypsin causes toxic reactions in most animals leading to various grades of diarrhea.
Studies showed that optimal heat treated soybeans resulted in a mean increase in milk production of 1.5kg per day
A 10% better feed conversion was obtained in lambs in extensive feedlot trails on roasted soya
Various studies have indicated that properly roasted soybeans are nutritionally superior to soybean meal in pigs.
An increase in the un-degradable intake protein from 25% to 60% takes place, thus the delivery of good quality protein to the animal’s digestive system.
When soybeans are processed through roasting, micronizing, flaking or extrusion, these processed soybeans effectively increase the conjugated linoleic acid (CLA) content in milk. Feeding raw soy beans has little or no effect on CLA.
Full-fat Soya has approximately 45±2% Protein and 28±2% Oil, compared to approximately 48±2% Protein and 6±1% Oil in oilcake meal. This is on a dry matter basis due to the extraction of the oil. (SunOpta Research)

horizontal feed ribbon mixer

A ribbon mixer is one used in manufacturing and industrial  

applications. Ribbon mixers are also occasionally called 

ribbon blenders. They are usually used when one of the 

items being mixed has a lot of particles, and it's important 

that all of the ingredients are mixed evenly. The mixer has a

 central shaft with mixing blades angled in different ways 

that look like ribbons of metal wrapped around the shaft, 

and is able to move parts of the mixture in different 

directions at the same time, ensuring that all ingredients 

are blended in. It can be used for food or medicine 

manufacturing as well as for heavier industry.

The ribbon mixer consists of some type of closed container, 

usually with a shape similar to a feed trough. The shaft with

 attached blades is located inside the container. The blades 

of the ribbon mixer look like two metal ribbons winding

 around the shaft, in a double helix design. It looks very 

similar to an illustration of a DNA strand. The ribbon mixer 

can have a horizontal construction, where the shaft and 

blade are sideways in the container, or the shaft and blade 

can be in a vertical position.

The horizontal feed mixer produced by Shandong Double Crane Machinery Manufacture Co.,Ltd. is very effective in feed mixing.Mixing is one of the most important operations in manufacturing of animal feeds. And mixer is considered to be the heart of feed milling operation. Single shaft double screw mixer is an efficient and versatile blending machine for mixing of dry granules & powders.

make feed pellets from alfalfa

What is Alfalfa?
The scientific name of alfalfa is Medicago sativa. It belongs to the legume family and it is a common raw material for making fodder pellets. Alfalfa is a high yield crop which is also particularly resistant to drought. It is now seen as the most popular and productive legume hay. In fact, it is the only forage pellets that is made and sold in every country.

Why Choose Alfalfa for Making Feed Pellets?

Alfalfa hay is the forage plant par excellence. It has great nutritional properties which makes it the perfect choice for making animal feed pellets.

High in nutrients: Alfalfa is an excellent source of vegetable protein, energy, vitamins, and minerals for animals including horse, pig and poultry. Besides, it is also rich in many other nutrients such as magnesium, molybdenum, sulfur, boron, calcium, potassium and phosphorus, etc. All these nutrients are good for animal healthy.

Rich in fiber: For ruminant animals, the fiber in alfalfa is fermentable by the large intestine and their digestibility can be highly improved in this way. The intake of fiber in animal feed is based on the particle size of the feed pellets.

Good for animals’ health: It is found that alfalfa has buffering effects on stomach acid, helping to reduce the incidence and and severity of gastric ulcers.
If you want to feed your animal with Alfalfa Pellets, there are two things to consider: Firstly change over to it gradually, and secondly try to limit it at first because its tastiness might lead to overeat. As a side benefit, alfalfa hay pellets are great ways to add water into forage as pellets can be soaked before feeding.

Drawbacks of Making Feed Pellets from Alfalfa

Alfalfa does provide a large amount of calories. However, if don’t burn the calories by taking exercise, it could result in weight gain. And gaining weight might be bad for some animal such as race-horse.

Because of its high calcium content, when making alfalfa pellets, it is necessary to keep an eye on the calcium-phosphorous ratio in the raw material mixture.

Alfalfa pellet mill can help you make dehydrated alfalfa hay into pellets or granules easily. Generally, the diameter of alfalfa pellets is made to be 6-8mm. Dehydrated alfalfa granules are ideal fodder for rabbits, ostriches, goats, pigs, sheep…

Why making alfalfa feed pellets?
Pellets form can largely reduce transport costs;
Make animal feeding easier and cleaner;
Enables the distribution of a protein food as a concentrate.

Shandong Double Crane Machinery Manufacture Co.,Ltd. is the professional manufacturer of all kinds of feed pellet machine, including feed hammer mill, feed mixer, ring die pellet mill and feed pellet cooler.

The benefits of pelletising

The benefits of pelletising:

Improved animal performance. Higher energy intake levels occur while animals spend less energy to graze.

Pelleted feed promotes animal growth due to better feed conversion rates, in other words better utilization of the nutrient value of the feed.

Due to the heat generated in the pelleting process, it improves the uptake of protein in the rumen of ruminants (thus a higher bypass protein),

 thereby increases amino acid availability and increases animal performance

Pelleting reduces wastage with up to 30% versus loose feeds, due to poor and selective eating habits

Pelleting will eliminate dust that will increase the palatability or taste of the feed

No wind loss occurs on pellets

Better mixing of raw materials takes place; therefore no selective feeding will take place.

The ration is less bulky and therefore reduces storage space requirements and allows for easier transportation and handling
