High quality freeze-dried pet food has the advantages of not losing natural nutrients, being loose and easy tor rehydrate, basically unchanged in color and shape, and being preserved for a long time at room temperature.
Therefore, high quality freeze-dried pet food sells well in the hot market. How to use pet food freeze-dried machine to process high quality freeze-dried pet food and do a good job in high quality freeze-dried pet food includes pet food freeze-drying technology and the purchase of pet food vacuum freeze-drying machine to meet the freeze-drying process.
High quality requires mature freeze dryer technology, mainly the following points:
1. Determine the eutectic point and eutectic point, such as chicken eutectic point is -20℃;
2. Determine the pre-freezing temperature and time according to the crystallization temperature requirements, such as the eutectic point temperature of chicken pre-freezing temperature should be below -35;
3. Determine the primary drying temperature, heating rate and drying time according to the crystallization temperature and eutectic temperature, and the primary drying limit high temperature of chicken is set according to the eutectic point;
4. According to the characteristics of the material and the temperature of the eutectic point to determine the temperature of analytical drying, heating rate, drying time;
5. Drying temperature, heating rate, drying time need to meet the material does not deformation does not collapse, does not change color, shell coking hardening affect food, ensure that the nutrients remain basically unchanged.
Pet food freeze dryer in dealing with a pet food material, need to be able to run automatically according to the freeze-drying technology data. Pet food freezing dryer chamber, baffle plate, the material plate adopts 304 stainless steel material, such as to ensure that the pet food safety non-polluting or material corrosion, need a clapboard temperature control range in - 45 ~ 90 ℃, extreme vacuum within the 3 pa, With heating rate control function and remote operation and monitoring function.
Because pet food freeze-drying function can produce high-quality freeze-dried pet food, so it is widely used in chicken breast freeze-dried, brittle bone freeze-dried, quail freeze-dried, beef freeze-dried, multi-spring fish freeze-dried, pet food additive freeze-dried pet food production and processing.
