A three-dimensional aseptic culture device for plant seed germination

Abstract

The invention relates to a plant seed germination three-dimensional aseptic cultivation device. The plant seed germination three-dimensional aseptic cultivation device includes a cultivation tank (54), a temperature humidity air regulating and control device (26) and an ultrasonic atomization tank (17). The cultivation device can achieve seed germination cultivation in an aseptic sealed state, canbe used for production of seed bud parching food, seed bud powder food auxiliary raw materials, and seed bud pulp beverage, and can meet the growth environment demand of germination cultivation of plant seeds such as nut fruits, cereal, vegetables and grass seeds.

Description

technical field [0001] The invention relates to a three-dimensional aseptic culture device for plant seed germination. Background technique [0002] In the 1940s, the first artificial climate chamber was established in Pasadena, California, and organically combined nutrient hydroponics and environmental control; in 1953, a large artificial climate chamber was built in Japan to carry out artificial climate control Cultivation experiments; in the mid-1980s, plant factories producing bean sprouts and other crops successively appeared in Chiba Prefecture, Tokyo and other places in Japan. [0003] The automatic bean sprouts production line developed by Japan Co., Ltd. Dasheng Machinery has a market share of 80% in Japan. Its production method is to produce in a fully sealed cultivation room. Each cultivation room can hold about 30 germination boxes. Put mung bean 50kg, realize the control to indoor temperature, humidity by computer program. [0004] So far, whether it is a larg...

Problems solved by technology

[0008] Any form of box-type open equipment, in the cultivation process relying on natural ventilation, if the seeds exceed a certain thickness, it is prone to poor water drainage, hypoxia, and local temperature and humidity out of control, resulting in seed hypoxia, root rot, and uneven germination; Due to the open equipment, the seeds cannot be cultivated in a sterile state, and the growth of microorganisms cannot be avoided, and the drop of foreign matter is the biggest drawback of the box-type open culture; CN200910094602.7 discloses an automatic seed soaking and accelerating germination device. The semi-open tank mouth does not have any sterilization measures for the seeds, so it is difficult to control the growth of microorganisms during the germination process; CN201210148305.8 discloses a device and its electrical control system based on biological germination technology. The problem of seed hypoxia and exhaled carbon dioxide emissions; the main hidden danger of food safety is the breeding of microorganisms and various foreign objects produced in the food production process, and the problems of water drainage, oxygen supply and temperature and humidity control of existing equipment cannot be effectively improved, limiting The further development and utilization of seed germination products in industrialized production, therefore, the existing technical equipment is not suitable as the front-end equipment for deep processing after seed germination
