Stevia rebaudiana seed harvesting device and method

Abstract

The invention discloses a stevia rebaudiana seed harvesting device and method. The device comprises a machine head, a collection box and a harvesting machine; the machine head buckles the collection box, and the harvesting device is communicated with the collection box; the machine head comprises a shell, a motor, a centrifugal fan and an air filter; the motor, the centrifugal fan and the air filter are located in the shell and arranged in sequence from top to bottom, and the motor is in transmission connection with the centrifugal fan and drives the centrifugal fan; an export port and an air-suction inlet are formed in the top and the bottom of the shell respectively, and a filter is arranged at the air-suction inlet; the harvesting machine comprises a suction nozzle, a handle and a hose;one end of the handle is connected with the suction nozzle, and the other end of the handle is communicated with the collection box through the hose. Accordingly, when mature seeds of stevia rebaudiana are harvested, the loss of seeds is less, the harvested seeds are mature seeds, and then the yield of the seeds is increased, and the quality of the seeds is improved; meanwhile, manpower and material resources are saved in the harvesting process, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a stevia seed harvesting device and method. Background technique [0002] Stevia is native to Paraguay and Brazil in South America, and is a subtropical perennial herb. The stevia sugar extracted from its leaves is 200-350 times sweeter than sucrose, and its calorific value is only 1 / 300 of sucrose; it is a natural sweetener with pure white color, pleasant taste and no peculiar smell; it is used for Food, beverage, medicine, daily chemical industry, wine making, cosmetics and other industries; regular consumption can prevent high blood pressure, diabetes, obesity, heart disease, dental caries and other diseases. The safety has been recognized by FAO and WHO, and it has been approved by the US FDA and the EU EFSA. It is known as "the third sugar source in the world"; as an emerging economic crop, in recent years, with the wide application of stevia With the contin...
