Abstract

The invention discloses a shiitake mushroom baking method, and aims to provide a shiitake mushroom baking method through which energy consumption can be reduced, and the heating uniformity of shiitakemushroom cap edges in the baking course of shiitake mushrooms can be effectively improved. The shiitake mushroom baking method sequentially comprises the following steps of firstly, a shiitake mushroom baking initial stage, wherein a wind return valve is closed, an exhaust valve and a fresh wind valve are both opened, a heat pump works, thermal air currents in a main wind channel enter an inner cavity of a baking chamber from a wind inlet of the baking chamber and form bottom-up flowing thermal air currents in baking chamber, then the thermal air currents in the baking chamber are dischargedfrom a wind outlet of the baking chamber and are charged into an evaporator chamber through a wind return channel and a wind exhaust channel, and besides, outside air enters the main wind channel through a fresh air channel; secondly, a shiitake mushroom baking maintaining stage, wherein the wind return valve is partially opened, the exhaust valve and the fresh wind valve are partially opened, andthe heat pump works; and thirdly, a shiitake mushroom baking accelerating and aroma increasing stage, wherein the wind return value is fully opened, the exhaust valve and the fresh wind valve are closed, and the heat pump works.

Description

technical field [0001] The invention relates to the field of shiitake mushroom drying, in particular to a shiitake mushroom drying method. Background technique [0002] Shiitake mushroom is a kind of edible fungus, which is very popular among consumers due to its delicious taste and high nutritional value. After the shiitake mushrooms are picked, the shiitake mushrooms should be processed and then packaged and sold. The most important process in the primary processing of shiitake mushrooms is the drying process, which plays a decisive role in the quality of dried shiitake mushrooms. [0003] In the traditional shiitake drying process, the gas is heated to the required temperature by burning wood, and then the high-temperature gas is sent into the drying chamber by a fan or an air pump to heat the shiitake mushrooms in the drying chamber. The consumption is large, the drying cost is increased, and the environment will be polluted and many other deficiencies. [0004] For t...
