The invention provides a quench device for a liquid packing vessel comprising a compressor which is used for compressing the refrigerant into high temperature high pressure gas, a condenser which transforms the refrigerant from the compressor into liquid state, an expansion valve which is used for decreasing the pressure of the refrigerant from the condenser for easy evaporation, an evaporator which is used for rapidly evaporating the liquid-state refrigerant from the expansion valve for rapid heat exchange. Besides, the top of the evaporator is directly provided with a liquid packing vessel for the evaporator having heat exchange directly with the liquid packing vessel. The invention can rapidly cool the liquid in the liquid packing vessel to shorten the cooling time.

The invention relates to a synchronous zero-contact roll paper box for preventing cross-infection, which belongs to the technical field of daily necessities; Roll paper pushing device, shearing device, lower cutter, first driving wheel, second driving wheel, third driving wheel, transmission rod, connecting shaft, top-tightening roller support device, roll paper support rod, third driving wheel are installed in the shell. One driving roller bar, the second driving roller bar, the first tight roller bar, the third driving roller bar, and the second tight roller bar. Through the ingenious design of the structure, the present invention solves the problem of unhygienic and easy to cause cross-infection caused by tearing the roll paper with both hands, and also solves the problem of electric roll paper box and handle-driven roll paper box in the prior art. During the process of switching or turning the handle, bacteria and viruses on the user's hands will remain on the switch or the handle, which will also cause cross-infection problems.

The invention discloses equipment for adding livestock and poultry manures to an earthworm bed. The equipment comprises a storage bin and a storage bin scraper type conveying chain, wherein a storage bin feeding opening and a retractable discharge opening are formed in the storage bin; a screw conveying shaft is arranged at the retractable discharge opening; the retractable discharge opening is connected with an inlet of a dispensing bin; a screw distributor and an anti-blocking device are arranged in the dispensing bin; a first bottom plate and a second bottom plate are arranged at the bottom of the dispensing bin; an elongated discharge opening is formed between the bottom edge of the first bottom plate and the bottom edge of the second bottom plate; and a first scraper type conveying chain and a second scraper type conveying chain which are used for pushing the livestock and poultry manures to the elongated discharge opening are arranged at the bottom edge of the first bottom plate and the bottom edge of the second bottom plate. By the equipment for adding the livestock and poultry manures to the earthworm bed, the problem of insanitation during manual addition of the livestock and poultry manures is solved, paving uniformity is guaranteed, and efficiency is improved; the livestock and poultry manures can be prevented from blocking the discharge opening, and an anti-blocking pin shaft rotates to prevent blockage of the livestock and poultry manures; accurate control of the thickness of a dispensing layer and uniform paving of the dispensing layer can be realized; and conveying and dispensing purposes can be achieved.
