Technical Field

The invention relates to the field of casing processing, in particular to a spacer-free circular tube and application thereof.

Background

The casing is a semitransparent film left after the intestinal canal of livestock is processed and other unnecessary tissues in the intestine are removed, is an ideal material for filling various sausages, and is mainly used for making sausages and casings for sausages. The existing known processing technology of natural casings is two types of dried casings and salted wet casings, in order to facilitate stuffing filling of sausage production enterprises, the casing production enterprises mostly use hard plastic round pipes as auxiliary materials for supporting casings, and because the lengths of the wet casings and the casings compressed on the plastic round pipes far exceed the lengths of the round pipes, in order to solve the problem that the casings slide off from two ends of the plastic round pipes, the casing production enterprises at present use rubber rings, elastomer rings or plastic spacers to sleeve the two ends of the plastic round pipes so as to prevent the casings from sliding off.

The existing traditional process has the following disadvantages: (1) the rubber ring, the elastomer ring and the plastic spacer can fall into sausage stuffing and be filled into the sausage casing in the sausage production process, so that the sausage is eaten by mistake or complained by consumers, and the sausage production enterprise is greatly troubled; (2) because the materials for preventing the sausage casing from sliding downwards meet the food sanitation standard, the cost is higher, which is equivalent to increase 80% of the auxiliary material cost, and great burden is added to sausage casing production enterprises; (3) the barrier materials are not convenient to assemble due to the need of tightening, and a large amount of labor is needed, so that the labor cost of casing manufacturers is increased; (4) the existing plastic circular tube is not lubricated enough due to the reasons of materials and processes, the speed is influenced by casing loading of casing production enterprises and casing unloading of sausage production enterprises, and the working efficiency is low.

At present, most sausage casing production enterprises use hard plastic circular pipes as sausage casing supporting auxiliary materials, the outer walls of the circular pipes are prevented from falling off, but some existing plastic circular pipes are inconvenient to operate and use as sausage casing supporting elements, and some plastic circular pipes can cause the slippage of some rubber elements on existing products, cause the mistaken eating of the elements and cause harm to the health of human bodies. In addition, the requirement of the lubrication degree of the plastic pipe for the sausage casing is important for the working efficiency, the lubrication degree between the plastic pipe and the sausage casing needs to be enough to enable the sausage casing to be quickly detached, but a certain degree of adsorption force is generated between the hose and the sausage casing of some existing products to be unfavorable for detaching the sausage casing, so that the working efficiency is reduced.

Compared with the prior art, the invention has the following beneficial effects:

the spacer-free circular tube is used for supporting parts of casings, the fixation of a rubber ring is omitted in the using process, the risk that the rubber ring falls off is avoided, the labor cost and raw materials are saved, in addition, the working efficiency can be effectively improved by performing special tabletting design on two ends of the circular tube, and the spacer-free circular tube has the excellent effects of convenience and easiness in operation. The invention can directly compress the sausage casing on the round tube without the process of firstly sleeving a spacer (or other barrier materials) on the round tube at one end and then compressing the spacer onto the round tube and then sleeving a stopping material at the other end.

The two ends of the spacer round tube are provided with two types of pressing sheets, one end of the spacer round tube is in an arc shape, the other end of the spacer round tube is in a square shape, and the directions for loading and unloading the sausage casings are distinguished by different shapes so as to meet the requirements of a sausage casing factory and a sausage factory for loading and unloading the sausage casings. After the sausage casing is filled on the circular tube, the sausage casing factory presses down the arc-shaped and square-shaped short parts at the two ends of the circular tube until the long parts are raised to form wing shapes to fix the sausage casing. When a sausage casing is dismounted in a sausage factory, one end (circular arc or square) of the sausage casing needs to be dismounted from the circular tube, and the long part is pressed until the short part is raised below the long part, so that the sausage casing is not prevented from being dismounted. The above two designs and operation methods for loading and unloading the casing. The efficiency of the operation is greatly improved whether it is a sausage casing producer or a sausage producer.
