Drying method for tea seeds

Abstract

The invention discloses a drying method for tea seeds. A drum-type frying machine, a drying machine and the tea seeds with moisture above 14% are adopted. The drying method comprises the following steps for drying: A) putting the tea seeds with moisture above 14% into the drum-type frying machine for frying, keeping the temperature in the drum-type frying machine at 145-153 DEG C, frying for 28-31 minutes when the moisture of the tea seeds is 18%, and frying for 30 minutes when the moisture is increased by 4% at each time; B) when the moisture of the tea seeds is about 14%, conveying the tea seeds into the drying machine, heating by the drying machine with a heat-transferring boiler, mounting U-shaped pipe series on three surfaces and upper and lower surfaces of the periphery of the drying machine, and then connecting by using stainless steel plates, thereby forming an oven, keeping oil temperature of heat-transferring oil at 60 DEG C, mounting an alarm in the oil tank, and directly alarming when the moisture of the tea seeds achieves 7% and the weight of a tray reaches 1.5 kg, wherein the alarm is in current connection and the spring tray is mounted under a wire. The drying method for the tea seeds has the beneficial effects of short drying time, convenience in control, energy conservation, environmental protection and good applicability.

Description

technical field [0001] The invention relates to a tea seed drying method. Background technique [0002] Tea seed is the seed of the camellia oleifera tree, which can be extracted for consumption. The extracted tea oil has extremely high nutritional value and health care effects. As the raw material for making camellia oil, tea seeds need to be dried to remove the moisture inside. However, the cost of drying tea seeds is high, the operation is inconvenient, and the drying time is long. Insufficient drying will directly affect the taste of tea seed oil. . Contents of the invention [0003] The invention provides a method for drying tea seeds, which can save costs, facilitate control, save energy and protect the environment, and ensure the effect of drying. [0004] The present invention adopts the following technical scheme: a method for drying tea seeds, comprising a drum-type frying dryer, a dryer and tea seeds with a moisture content of more than 14%, which are dried th...
