Dragon Fruit Powder Freeze Dryer

Dragon Fruit Powder Freeze Dryer

Dragon Fruit Powder Freeze Dryer adopts the method of radiation heating; the heat is transferred from the heat radiation plate to the surface of the drying layer of the material by radiation, and then reaches the sublimation interface from the surface of the drying layer by means of heat conduction and gas convection. The directions of radiative heat transfer and mass transfer are opposite, and the internal frozen layer temperature is determined by the balance of heat transfer and mass transfer.

The characteristic of general radiant heating is that as the sublimation surface shrinks inward during the drying process, the thickness of the dried layer becomes thicker and thicker, and the resistance of heat transfer and mass transfer increases at the same time. Radiant heat transfer can overcome the shortcomings of contact heat transfer, and it is easy to ensure the quality of products, but the time required is relatively long.

This design mainly studies the vacuum freeze-drying production process and workshop layout of the Dragon Fruit Powder Freeze Dryer. At the same time, the hazard analysis of the production process is carried out, the key control points are determined, and the HACCP plan is formulated for the product. Taking into account the needs of enterprises to produce different products, the selected equipment can meet the needs of production.

The production process of dragon fruit powder vacuum freeze-drying mainly consists of raw material acceptance, sorting, cleaning, peeling, slicing, adding protective agent, pre-drying, pre-freezing, vacuum freeze drying, crushing, mixing, inner packaging, metal detection, outer packaging, etc. composition. The floor plan of the production workshop is designed according to the production process to avoid the intersection of people and logistics and meet the production requirements and hygiene requirements. At the same time, the design of doors, windows, walls, lighting, ventilation, and other aspects are designed according to the needs of the workshop. According to the relevant standards and the actual situation, the auxiliary department of the food factory has been planned to some extent.
