Hot a ir circulation oven adopts noise elimination and thermal stable axial flow fan and automatic temperature control system. The entire circulation system is enclosed to make that the heat efficiency of the drying oven increases from 3~7% of the traditional drying oven to 35~45% of the present one. The highest heat efciency can be up to 50%. The successful design of hot air circulation oven makes that the hot air circulation drying oven in our country reach the advanced level in the world. It saves energy and increases the economic benet. In1990,the medical management bureau of the State issued the industry standard and the uniform type is RXH.
It is mainly used for the drying of agricultural and sideline products such as fruits and vegetables, Chinese herbal medicines, pet foods, etc. Due to the use of hot air convection heating, there is absolutely no pollution to the products, which is in full compliance with food hygiene standards. Hot air is recyclable and thermal efficiency is significantly improved. The baking tray can be made of plastic mesh plate or stainless steel mesh plate, and can also be flexible and convenient by using wooden strips, wire mesh, bamboo nets and sieves.
