Freeze Dryer For Pet Food
The difference between pet freeze-dried food and ordinary pet food is that the existing pet food is mostly expanded and dried products, and its main components are mostly grain, vegetables and meat. Its processing method is usually made by mixing grain, vegetables and meat crushing materials, adding additives, water and other auxiliary materials, placing them in molds or drying rooms, expanding or baking at high temperature. It can be seen that the existing pet food is made by heating and baking, which not only loses the flavor of the original ingredients, but also causes a large loss of nutrition. The pet food freeze-drying technology overcomes the shortcomings of the prior art. The pet freeze-dried snack made by the freeze-drying method has the advantages of high nutritional composition, retaining the original flavor and good rehydration.
What are the benefits of freeze-drying pet food? Its advantages are as follows: 1. Using real materials, the food materials can be seen; 2. High nutrition, original flavor; 3. Extremely low water content and easy to preserve; 4. Light weight, easy to carry; 6. Super high palatability, pet likes to eat; 7. High rehydration, nearly fresh.
Freeze dryer for pet food can be used for a small amount of freeze-drying or product development!The freeze-drying technology of pet food products mainly includes raw material selection, pretreatment, low-temperature pre freezing, freeze-drying and packaging.
1. Raw material selection
Choice of raw materials, choose fresh chicken, duck, beef, mutton, fish and so on.
2. Pretreatment
The selected raw materials are processed before freeze-drying. Different materials have different pretreatment processes. Generally, the materials are cut into the required shape, and then cleaned, blanched, sterilized, etc. The purpose is to remove sundries, sublimate and dry them, and prevent oxidative deterioration caused by excessive fat and chemical deterioration caused by autolytic enzyme activities in meat. After processing, these materials will be put into the tray for the next step.
3. Low temperature pre freezing
Solidify the free water in meat ingredients, so that the finished products after drying have the same shape as before drying, prevent irreversible changes such as foaming, concentration, shrinkage and solute movement during vacuum drying, and reduce the decrease of material solubility and changes in life characteristics caused by temperature drop.
After the pretreatment, the raw materials will be frozen in the fast freezing warehouse with a temperature of minus tens of degrees. During the pre freezing, the pre freezing will be carried out according to the pre freezing rate, the minimum pre freezing temperature and the pre freezing time. Generally, the vacuum sublimation can be started 1-2 hours after the temperature of the materials reaches the minimum pre freezing temperature.
4. Freeze drying
Freeze drying is generally divided into two steps and stages: sublimation drying and desorption drying. Sublimation drying is also called the first stage drying. The frozen product is heated in a closed vacuum container. When all ice crystals are removed, the first stage drying is completed. At this time, about 90% of all water is removed. Drying starts from the outer surface and gradually moves inward. The residual gap left after ice crystal sublimation becomes the escape channel of sublimated water vapor.
Desorption drying is also called the second stage drying. Once the ice in the product is sublimated, the drying of the product enters the second stage. After the first stage of drying, some water is adsorbed on the capillary wall and polar groups of the dried material, which is not frozen. When they reach a certain content, they provide conditions for the growth and reproduction of microorganisms and some reactions. In order to make the product reach the qualified residual moisture content, improve the storage stability of the product and prolong the storage life, the product must be further dried. After the second stage drying, the content of residual moisture in the product depends on the product type and requirements. Generally between 0.45% - 4%.
5. Finished product packaging
Seal the freeze-dried pet food to avoid moisture regain.
