Cattle and sheep sperm drying oven

Abstract

The invention discloses a cattle and sheep sperm drying oven which comprises an oven body and a door plate, wherein the door plate is arranged on the oven body; on end of the door plate is moveably connected with the side wall of the oven body; a first chute is formed in the oven body; a first carrying plate is arranged inside the first chute in a penetration manner; a plurality of second carryingplates are arranged on the first carrying plate; glass slides are arranged on the second carrying plates; a first gas storage tank and a second gas storage tank are arranged at the top of the oven body; the first gas storage tank and the second gas storage tank are connected through a connecting tube; the connecting tube is internally provided with a driving motor; a plurality of blades are arranged on the output shaft of the driving motor; the second gas storage tank is internally provided with a heating block; and the first gas storage tank and the second gas storage tank respectively communicate with the oven body. Through circulation of nitrogen, nitrogen does not need to be recharged after being charged for a first time, so that loss of nitrogen is reduced, and operators can be prevented from damage of nitrogen which is excessively discharged into the air.

Description

technical field [0001] The invention belongs to the technical field of biological cell preservation, in particular to a drying box for bovine and sheep sperm. Background technique [0002] The routine preservation of sperm mainly includes cryopreservation and room temperature preservation. Conventional cryopreservation techniques require liquid nitrogen or dry ice. Among them, liquid nitrogen not only requires special steel tanks, but also is dangerous, which brings great inconvenience to transportation; while dry ice is easy to melt at room temperature, which has limitations such as inconvenient transportation, high storage costs, and short storage time. [0003] Since the introduction of intracytoplasmic sperm injection (ICSI), many simpler methods of semen preservation have been investigated, including freeze-drying and evaporative drying. After drying, semen can not only be stored at 4°C for a long time, but also can be transported and stored for a short time at room te...

AI Technical Summary

Problems solved by technology

The use of nitrogen in this method requires the use of special nitrogen cylinders, and during the purging process, the loss of nitrogen is serious, the cost is high, the operation is complicated, and there is great danger in the operation process.

However, the method of evaporative drying in a natural environment has low drying efficiency, and with the increase of drying time, the integrity rate of semen chromosomes will be greatly affected
