AI Technical Summary
Existing camel milk drying technologies suffer from problems such as nutrient loss due to high temperatures, risk of microbial contamination, long drying cycles, and low efficiency. In particular, high-temperature spray tower processes and vacuum drying equipment with fixed tray structures cannot effectively protect the heat-sensitive components of camel milk and ensure uniform drying.
The fully automatic low-temperature vacuum drying device uses a rotary drying cylinder and vacuum section design, combined with a heating plate and gas-liquid separator, to achieve rapid and uniform drying of camel milk at low temperature. The vacuum pump maintains a negative pressure environment and the dynamic sealing interface ensures drying efficiency and prevents camel milk from contacting air.
It achieves low-temperature, high-efficiency, and pollution-free drying of camel milk, resulting in high nutrient retention, good drying uniformity, and avoidance of clumping, thus improving product quality and safety.

TECHNICAL FIELD
[0001] The utility model belongs to the food processing technical field, specifically is full -automatic low temperature vacuum drying device. BACKGROUND
[0002] Camel milk becomes a research hotspot in recent years because of its unique nutritional value and health care function, and its nutritional components not only contain high concentration of immunoglobulin, lactoferrin and other bioactive substances, but also are rich in vitamins, minerals and unsaturated fatty acids, and the comprehensive nutritional value is far more than cow milk and other animal milk. However, these precious heat-sensitive components in camel milk also bring great challenges to the processing process.
[0003] The existing camel milk drying technology mainly adopts high-temperature spray tower process, which atomizes and dehydrates the emulsion by high-temperature airflow above 180 DEG C. Although this method can quickly realize dehydration, it can cause a large loss of heat-sensitive active components such as immunoglobulin (IgG), lactoferrin, lysozyme, etc. in camel milk, and the nutrient retention rate is less than 50%. More seriously, the high-temperature environment can destroy the natural structure of the protein, trigger denaturation reaction, and accelerate fat oxidation, resulting in the appearance of oxidation and brown phenomenon of milk powder. In addition, the open processing process also increases the risk of microbial contamination, further affecting the safety and quality of the product.
[0004] Some existing vacuum drying equipment adopts a fixed tray structure, which can avoid the damage of high temperature to camel milk, but during the drying process, the camel milk surface is easy to form a film, which hinders the migration of internal moisture, resulting in a drying period of 8-12 hours. This long-time static drying not only has low efficiency, but also causes the water to form a gradient distribution in the camel milk, which makes the rehydration of the finished product poor, and the camel milk powder is easy to form a lump during dissolution, affecting the brewing experience and nutritional value release of the camel milk powder.
