Self-cleaning double-needle injection needle assembly for saline injection machine

Abstract

The invention discloses a self-cleaning double-needle injection needle assembly for a saline injection machine. The self-cleaning double-needle injection needle assembly comprises needles, a solutiondistributor, an electromagnetic reversing valve, a force measuring sensor, a solution filling pipe joint and a cleaner filling pipe joint. The solution filling pipe joint and the cleaner filling pipejoint are connected with the solution distributor by the electromagnetic reversing valve, pipelines can be communicated with one another and can be disconnected from one another, resistance can be detected by the force measuring sensor when puncture is carried out by the needles, and the solution distributor can be filled with cleaners or high-pressure pulse water by the aid of the cleaner fillingpipe joint, so that the solution distributor and the needles can be cleaned or dredged. The self-cleaning double-needle injection needle assembly has the advantages that the needle blocking probability and the operation cost can be lowered, and accordingly the economic benefit can be increased; periodic cleaning is carried out, accordingly, the bacteria breeding opportunity can be reduced, and the quality and the quality stability of meat products can be improved; the force measuring sensor is used, accordingly, the needles can be effectively prevented from being bent or broken off, and damage can be prevented; the self-cleaning double-needle injection needle assembly is simple in structure, high in safety and adaptability, easy and convenient to operate and maintain and suitable for popularization, and the like.

Description

Technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a self-cleaning double-ended injection needle for a saline injection machine with functions of cleaning, preventing clogging and avoiding needle bending and breaking. Background technique [0002] The brine injection machine injects salt water, flavoring agents, preservatives, etc. into the meat products to fully marinate. The meat pieces injected into the prepared aqueous solution can make the meat quickly marinate, increase flavoring, tenderization, and softness, and can also maintain the nutrition and strengthen the meat. The taste improves the taste and yield of meat products. The injection needle of the existing injection machine has an unreasonable design structure, short service life, high failure rate during use, and inconvenient operation. When traditional saline injection machines are in use, problems such as needle blockage, leakage, difficult...

AI Technical Summary

Problems solved by technology

The patent mainly has the following problems in actual operation: when the injection tube head hits a hard object, the injection tube will automatically bounce, and other injection tubes will also bounce up, which will affect the injection efficiency; the length of the injection tubes is consistent, which is easy to cause Meat products are injected unevenly, with different tastes inside and outside, and the diameter of the injection tube is required to be large

The Chinese patent with the application number 201620641879.2 discloses an injection nozzle of a saline injection machine, including a saline distributor and an injection mechanism. By adjusting the length of the injection tube, uniform injection is ensured, but when the injection tube is blocked, the method of unblocking it with a fixed needle Too cumbersome and inconvenient to clean

The Chinese patent with the application number 201621105483.2 discloses a saline injection machine, which avoids the direct contact between the injection needle and the meat product by opening the foot structure, and can solve the problem of injection needle blockage. The disadvantage is that the opening foot takes up a lot of space. Not suitable for use in some occasions with dense needle tubes

The Chinese patent with application number 201120357352.4 discloses a saline injection machine. By adding multi-channel filtration to the solution tank car, the probability of clogging the injection needle is reduced. The disadvantage is that it is not suitable for some occasions where the needle tubes are dense and the space is small.

The Chinese patent with the application number 201320368008.4 discloses a pneumatic pop-up device for the injection needle of a saline injection machine, which includes a pressure regulating valve, a sealed air chamber and an injection needle. The problem of bending if it is too large can not solve the problem of needle blockage
