Oil tea fruit pretreatment flotation machine and method

Abstract

The invention belongs to the field of food processing equipment, and particularly discloses an oil tea fruit pretreatment flotation machine and method. The flotation machine comprises a flotation machine body, a solution recycling device and a circulation liquid preparing device. The flotation machine body comprises a flotation tank, and the two sides of the flotation tank serve as the feeding endand the discharging end. The feeding end is provided with a liquid supplementing hole and a liquid return hole. The bottom of the flotation tank is of a U-shaped structure, and a flotation circulation conveying belt and a flow guiding obstruction baffle are arranged inside. The flotation circulation conveying belt comprises a horizontal section and an inclination section, wherein the horizontal section is immersed in flotation liquid. The lower end of the flow guiding obstruction baffle is immersed in the flotation liquid, the upper end of the flow guiding obstruction baffle is higher than the liquid level of the flotation liquid so that fruit shells can be stopped and gathered, and the fruit shells are discharged into a fruit shell guide-out groove through a fruit shell removal stirringplate device. The solution recycling device is connected with the fruit shell guide-out groove, and the circulation liquid preparing device is used for achieving flotation liquid supplementing. The flotation machine is utilized in the method for tea seed and fruit shell sorting. The oil tea fruit pretreatment flotation machine and method have the beneficial effects that the tea seed sorting effectis good, and the labor intensity and production cost are low.

Description

technical field [0001] The invention belongs to the field of food processing equipment, and more specifically relates to a flotation machine and method for pretreatment of camellia oleifera fruit. Background technique [0002] Camellia oleifera is a unique woody edible oil tree species in my country. Its fruit is composed of two parts: camellia oleifera husk and tea seed. Among them, tea seed can be used as raw material for edible oil, feed and chemical products, and the husk can be used to prepare activated carbon, tannin extract, High value-added products such as culture medium and saponin. Camellia oleifera fruit should be harvested in time when it is ripe. Traditionally, the husk will fall off by turning over the sun, and the camellia oleifera seeds are stored in a ventilated and dry place. However, due to the package of camellia oleifera husk, the moisture is not easy to dry in the sun, and there are often rainy days during the harvest season, which can easily cause the...
