Composition and working process of dehydrated vegetable hot air circulation oven

The dehydrated vegetable hot air circulation oven is mainly composed of angle steel, stainless steel plate and cold steel plate. The air circulation system adopts the fan circulating air supply mode, and the air circulation is even and efficient. The equipment adopts 100-level purification hot air circulation laminar flow purification technology, and is equipped with computer automatic control system. It uses automatic ventilation to realize automatic constant temperature control and fully closed cycle operation, which fully meets the requirements of production specifications.

Most of the components of the dehydrated vegetable hot air circulation oven are made of stainless steel, which reduces the contamination caused by the corrosion of the parts. The dehydrated vegetable hot air circulation oven uses steam or electricity as a heat source to heat the air by convection of the axial flow fan heat exchanger. The warm air layer transfers heat through the baking pot and the material. Fresh air enters from the air inlet and then replenishes fresh air and continuous hot air from the exhaust port, so maintain proper relative humidity. The dehydrated vegetable hot air circulation oven air circulation system adopts the fan circulation air supply mode, and the air circulation is uniform and efficient. The wind source is driven by a circulating air supply motor (using a non-contact switch) to drive the wind wheel through the heater, and the hot air is sent out, and then the air is taken into the air chamber through the air passage, and then the used air is sucked into the air passage to be recirculated as a wind source. Use for heating. Ensure indoor temperature uniformity. When the temperature value oscillates due to the operation of the switch door, the air circulation system quickly returns to the operating state until the set temperature value is reached.

The characteristic feature of the oven in the dehydrated vegetable hot air circulation oven is that most of the hot air circulates inside the box, thereby improving heat transfer and saving energy. The oven's thermal efficiency is 3% from the traditional drying chamber, 8% to the current 35% -50%, it uses the forced ventilation effect to reduce the temperature difference. Dehydrated vegetable hot air circulation oven drying equipment is common and widely used. It is a disc type batch drying equipment used for raw materials, products, heating and dehumidification of pharmaceutical, chemical, food, light industry, heavy industry. Heating steam heat, electricity, far infrared electric steam dual-use, for users to choose. Since the hot air circulates through the circulation passage in the oven body, there is no additional circulation duct, which reduces the loss of heat and achieves the purpose of energy saving. After the air is heated by steam to heat the fins or the electric heater, the heat is directly exchanged with the material, and at the same time, the air that has undergone heat exchange with the material is dehumidified, which is beneficial to improve heat exchange efficiency. The electric heater and the steam heating fins are arranged separately, so that the entire oven is compact and small in size.
