The temperature of described hothouse is increased to 25 DEG C by 10 DEG C from front to back, and humidity is reduced to 30% by 70%, and it is interval that best hothouse is divided into several.
The utility model compared with prior art has the advantage that
(1) the vermicelli quality processing is good, can be substantially improved local flavor, the mouthfeel of vermicelli, and vermicelli have a kind of elasticity, smooth, the sensation of chewy after cooking simultaneously;
(2) improve dry tenacity, shorten drying time, add the efficiency of equipment, thus reach the comprehensive economic index of unit product, than traditional handicraft shorten drying time 1.5 little when, chain week line speed original frequency conversion 35HZ is brought up to 50HZ;
(4) saving heating agent cost, compared with traditional technique, every day (10 hours) reduces cost 700 yuan;
(5) eliminate dehumidifier operation, process 2 tons of vermicelli and can save power consumption 45KW;
