Introduction to oyster：

  After the harvested oysters are shelled, washed, soaked, and blanched in boiling water, first ensure the integrity of the oyster meat when shelling, and then use clean water to clear the shell residue, and then soak in a basin to remove some mucus. , In this way, it can be blanched again in boiling water. The blanched oysters are immediately placed in the material tray, and the material tray is inserted into the material truck and pushed into the drying room.

Oyster drying process：

  The drying system uses a 6P heat pump to dry and dehumidify. The host is equipped with a polyurethane insulation room with a length of 5.8 meters, a length of 3 meters and a width of 2.2 meters. The room is equipped with 8 250W axial circulation fans to dissipate the heat to the shaft through the internal evaporator. The air flow circulation fan blows out from the rear, passes through the material truck in parallel, and returns to the return air inlet. There is a return air fan at the return air inlet for dehumidification, so that the air path in the drying room forms a push-pull form, and the wind speed becomes faster, uniform, and beneficial. Balanced dehumidification, the high-temperature and high-humidity wind returned from the return air vent is heat recovered by the host, and is condensed into water through the condenser and then discharged. In this way, the dry hot air circulates continuously until the oysters are completely dried.
  The 6P drying and dehumidification system fills 1200 kilograms of fresh oysters at a time, the dehumidification capacity of the main unit is 25L per hour, and the temperature is set between 55°C-65°C. Each batch takes about 20 hours. The oysters are dehydrated after drying. The ratio is generally around 5 to 1. Under the condition of ensuring the temperature in the drying room, increasing the dehumidification capacity and speed can effectively shorten the time.

Recommendation of oyster 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.
