Plant cell culture sterile drying equipment

Abstract

The invention discloses plant cell culture sterile drying equipment. The plant cell culture sterile drying equipment structurally comprises more than two drying ovens, an operation table and bottom brackets; the drying ovens are horizontally arranged in a row; the operation table is arranged on one sides of the drying ovens; the operation table is electrically connected with the bottoms of the drying ovens; the bottom brackets are arranged at the bottommost parts of the drying ovens; each drying oven is composed of a communicating pipe, a placing panel, an oven body, a connecting pipe and a heating piece, the communicating pipe is arranged in the middle of the top end of the oven body, arc-shaped notches are formed in the periphery of the placing panel, air transpiration is carried out atfour corners of the placing panel, so that formation of local pressure is prevented, the heating temperature of a top layer and the heating temperature of a bottom layer are ensured to be the same, and the pressures are ensured to be the same. Vessel fixing devices used for containing vessels are installed on the placing panels, vent holes are further formed between every two adjacent vessel fixing devices, each vent hole is in a sandglass shape, the diameters of the upper portion and the lower portion of each vent hole are large, the diameter of the middle of each vent hole is small, gas sinking and gas rising are accelerated firstly and then slow, and vessel overturning caused by gas upwelling is avoided.

Description

technical field [0001] The invention relates to the field of medium sterilization, in particular to a plant cell culture aseptic drying equipment. Background technique [0002] The bioreactor for cultivating plant cells, tissues and organs has reached the stage of industrialization and biochemistry. The culture materials used for plant cell culture, such as agar, cannot be directly used for plant cell culture. The nutrient content in agar will be relatively high, which is easy to breed bacteria , to destroy the cultivation of plant cells, so aseptic drying equipment is required for sterilization in the middle, because it is placed in batches in petri dishes for sterilization and adopts upper and lower layers, and the bottom and bottom are not circulated. When the temperature rises for sterilization, the temperature Unevenness leads to uneven local pressure, and the petri dishes placed on the shelf will float, causing the agar culture to pour out. In addition, uneven temperat...

[0002] The bioreactor for cultivating plant cells, tissues and organs has reached the stage of industrialization and biochemistry. The culture materials used for plant cell culture, such as agar, cannot be directly used for plant cell culture. The nutrient content in agar will be relatively high, which is easy to breed bacteria , to destroy the cultivation of plant cells, so aseptic drying equipment is required for sterilization in the middle, because it is placed in batches in petri dishes for sterilization and adopts upper and lower layers, and the bottom and bottom are not circulated. When the temperature rises for sterilization, the temperature Unevenness leads to uneven local pressure, and the petri dish placed on the shelf will float, causing the agar culture to pour out. In addition, uneven temperature is also prone to uneven drying at the top and bottom of the shelf, resulting in low efficiency
