Introduction to maca：

  Maca is rich in high-unit nutrients and has the function of nourishing and strengthening the body. Maca is native to high-altitude mountainous areas, suitable for growing in high-altitude, low-latitude, high temperature difference between day and night, slightly acidic sandy soil, and sunny land.

Maca drying process：

  During the baking process, it is necessary to master the three processes of temperature from low temperature to high temperature + cooling.
  When entering the furnace in the first stage, because the water content is still high, the temperature is gradually increased and maintained for 12-15 hours to gradually evaporate the water. The temperature is adjusted at 35°C-45"C, and the humidity is set to 30% to automatically dehumidify. Continue for about 1 day to discharge most of the water. The temperature in the second stage is gradually increased and set at 55°C-60°C to evaporate the water. The humidity is adjusted at 38% to automatically dehumidify and let the water vapor discharge. This continues for 12 Hours to drain most of the water. In the third stage, the temperature is lowered to 45°C-55°C, the humidity is adjusted to 35%, and the baking is continued until drying, so that the weight of the fruit is reduced to 25-30% of the fresh fruit. Serve dried fruit. After drying, close it and let it cool down naturally, and then take it out after cooling down.
  During the drying process, the upper, middle, lower, surrounding and center of the baking tray, the upper and lower temperatures of each fruit are different, in order to make the heating even, except for the first day, the upper and middle should be heated every day. , The lower oven changes the levels, turning and pressing the edge and center fruits to achieve consistent heating. Due to differences in maca quality, maturity and size, individual maca that cannot be dried in the first drying operation should be selected and re-dried.
  When the maca is just picked, the water content is 70%, and it is suitable to be stored at a water content of 10-20%, and the drying temperature is below 50°C. It is recommended to use two units to dry the maca in the form of bidirectional left and right convection, so that the drying temperature is even.

Recommendation of maca dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
