FD Pet Food Vacuum Freeze Drying Machine

As a natural dairy product with low fat, high calcium, beauty, and anti-aging properties, donkey milk has health benefits for various organs such as the heart, stomach, spleen, lungs, liver, and prostate of the human body. Its nutritional content is close to 99% of human milk, making it a treasure of breast milk. The calcium to phosphorus ratio in donkey milk is 1.77:1, which is very similar to the 2:1 ratio in human milk and is easy to absorb and utilize. Donkey milk contains various amino acids needed by the human body, with a high content of essential fatty acids. In addition, donkey milk is rich in trace element selenium, which is 5.2 times that of milk. It is a natural selenium rich food. According to research reports, donkey milk contains a large amount of epithelial cell growth factor EGF, which has the effect of improving human immunity and increasing resistance. The sentence is:.

　　Fresh donkey milk vacuum freeze-drying machine, pet food freeze-drying equipmentIt is a processing equipment that performs heat and mass transfer on freeze-dried materials in a vacuum low-temperature environment. It is an interdisciplinary comprehensive technology. Freeze drying requires support from technologies such as vacuum, refrigeration, heating, mechanical transmission, and automatic control. The application scope of vacuum freeze-drying technology is very wide. Any substance that contains water and is non corrosive can be made into freeze-dried products using freeze-drying technology. Almost all agricultural and sideline products such as meat, poultry, eggs, aquatic products, vegetables, etc. can be made into freeze-dried products. At present, freeze-drying technology is widely used in the food industry, biopharmaceutical industry, medical industry, health product industry, nano materials, and other industries.

Vacuum freeze-drying, also known as freeze-drying, is a drying technology that freezes wet materials or solutions into a solid state at a lower temperature, and then directly sublimates the water in the liquid state into a gas state under vacuum, ultimately dehydrating the material.

1. Storage of raw materials: Collect fresh and uncontaminated donkey milk using a sterile filling truck, sterilize it at 200MPa for 300 seconds, and store it at -30 ℃ -0 ℃ to form frozen donkey milk;

2. Raw material de icing pretreatment: Aseptically clean the de icing tank, add frozen donkey milk, cover the sealed de icing tank, start the mixer, and stir at a speed of 200r/min-300r/min for 10-20 minutes;

3. Ice melting: Hot water or steam is circulated through the interlayer of the ice melting tank using liquid heating or steam heating methods to heat the tank until frozen donkey milk * melts. The temperature of the heated donkey milk is controlled between 50 ℃ -70 ℃;

4. Emulsification: Aseptically clean the colloid mill, suck the thawed donkey milk into the colloid mill through a sanitary pump, run the colloid mill for 3 minutes, and then transfer it to the storage tank through a homogenizer;

5. Sterilization: Heat and sterilize the plate sterilizer and feeding tube at a pressure of 0.15MPa-0.3MPa and a cleaning and sterilization temperature of 98 ℃ until the outlet water temperature is between 85 ℃ -98 ℃ and the return water temperature reaches 60 ℃ or above. Pump the donkey milk in the storage tank into the plate sterilizer for sterilization. The sterilization temperature of the plate sterilizer is 72 ℃ -85 ℃, and the insulation time is 15s-45s. After sterilization, the donkey milk is directly connected to the quantitative automatic feeding device of the Red Deer freeze-drying machine for freeze-drying or to an intermediate storage tank that has been sprayed with 90 ℃ hot water for 5 minutes for concentration;
