Abstract

The utility model discloses a machine for squeezing fruit juice and vegetable juice. The machine is composed of a charging barrel, a screw rod, and a back pressing plate, wherein the screw rod in the charging barrel has a twin-screw structure, a front end outlet of the charging barrel is provided with the back pressing plate which is a piston in a cylinder, and the cylinder is switched with an air supply by a guide tube. The utility model has the characteristics of large treating capacity, no need of an additional fruit residue anti-rotary device and easy automatic control, and stable juice output rate and production quality can be obtained.

Description

Fruit ﹠ vegetable juice squeezer

The utility model relates to the machinery of a kind of squeezing juice, vegetable juice.

Existing fruit press equipment is most to adopt single screw rod that pressure is provided.Because screw diameter is subjected to the restriction of fruit juice discharge path, so the treating capacity of single screw rod extruding is very little.Simultaneously, pomace is together rotated in company with screw rod and stops up the pomace passing away when turning round owing to screw rod, must be equipped with the device that prevents the pomace rotation, and the running efficiency of equipment is reduced, and equipment failure rate increases, and cleans difficulty.

The purpose of this utility model is to provide a kind for the treatment of capacity big, need not add the Fruit ﹠ vegetable juice squeezer of pomace anti-rotation device.

The purpose of this utility model is achieved in that it is made of barrel, screw rod, back pressure plate.Screw rod in the barrel is a double-screw structure, and the front end exit of barrel is installed the back pressure plate.Because screw rod is sheared, is pushed fruit, vegetables etc., therefore can be with its tooth depth and the ratio increase in screw rod footpath, the twin-screw tooth depth can be more than 1: 5 with the ratio in screw rod footpath.Can obviously improve the extrusion capability of screw rod like this.

Back pressure plate of the present utility model is a piston in cylinder, and cylinder is connected source of the gas by conduit, and bleed pressure is constant.Adopt such pneumatic means as the back pressure plate, can make the extruding of barrel keep constant, because extruding force is constant, the water content of discharging pomace also is constant, so can obtain stable crushing juice rate and product quality.

The utility model compares with single screw rod juice extractor, and its treating capacity improves widely, and because the mutual cleaning action of twin-screw engagement, stopped the pomace clogging, therefore need not add the pomace Device for preventing rotation, running efficiency is improved, fault rate reduces, and cleans to become convenient.It is to adopt the outlet gap realization of manually regulating back pressure plate and barrel by screw mandrel that the pressure of the existing in addition equipment of squeezing the juice is regulated.In this manual adjustment mode, the extruding force of squeezing the juice constantly changes with factor such as charging rate, charging degree of grinding and water content, thereby the quality of squeezing the juice can not be guaranteed.Adopt pneumatic shuttle can make the extruding force of barrel keep constant, the feasible quality of squeezing the juice can be guaranteed.Because the extruding force of processing is by the pressure decision of source of the gas, be easy to production process be controlled automatically in addition with common compress control method.

By the following examples and in conjunction with the accompanying drawings the utility model is further described.

Fig. 1 is an example structure schematic diagram.The 1st, screw rod, the 2nd, barrel, the 3rd, back pressure plate, the 4th, cylinder.Barrel 2 is identical with common single screw cylinder structure, on the barrel wall fluid hole is arranged, and from then on the Juice of squeezing out flows out in the hole.Screw rod 3 in the barrel 2 is twin-screw forms, and the tooth depth of screw rod 3 can be 1: 3 with the ratio in screw rod footpath.Intermeshing twin-screw provides extruding force, at the front end of barrel 2 back pressure plate 3 is arranged, and back pressure plate 3 is pistons of a cylinder 4, and cylinder 4 is connected constant source of the gas by conduit.Between back pressure plate 3 and the barrel 2 slit is arranged, pomace is discharged from here.Because back pressure plate 4 is to connect with constant source of the gas, so the pressure of back pressure plate 3 also is constant, thereby can guarantee the constant of extruding forces in the barrel 2.
