Abstract
A mini program freezer includes a main box, a liquid nitrogen box, a diaphragm pump, and a solenoid valve. A nitrogen delivery pipe is arranged in the liquid nitrogen box, and a through hole is arranged at the bottom of the nitrogen delivery pipe; the diaphragm pump is connected to the air inlet end of the nitrogen delivery pipe through a pipeline through the solenoid valve; the main box is provided with an insulation layer, a nitrogen delivery layer, and a freezing layer from the outside to the inside in sequence; a plurality of vents are arranged on each wall of the freezing layer, and a frame for placing frozen sperm tubes in multiple layers in the freezing layer is provided, and a plurality of grooves are arranged on each layer; the air outlet end of the nitrogen delivery pipe is inserted into the nitrogen delivery layer. The effect is: no self-pressurized liquid nitrogen tank is used or positive pressure gas is injected into the liquid nitrogen tank, thereby reducing the use cost; the freezer adopts the siphon principle to blow positive pressure gas into the cavity, thereby bringing in liquid nitrogen, reducing the design cost of the equipment, and the amount of liquid nitrogen used can be controlled and observed, and the freezing amount is small, the machine size is small, and does not occupy a large space; it is light in weight, suitable for carrying, and there is no external large liquid nitrogen tank, which is flexible and mobile for freezing small batches of frozen sperm tubes.
