Quantitative filling valve containing pulp type beverage

Abstract

The invention discloses a quantitative filling valve for pulp beverages, wherein a plunger is inserted into a cavity of a valve seat; an operational ring is arranged in the lower part of the valve seat; a feed port is provided on the operational ring, corresponding to an opening of the valve seat; a discharge port is provided in lower part of the valve seat, corresponding to a valve nozzle; the feed port and the discharge port are both communicated with the cavity of the valve seat; the operational ring is rotated inside the valve seat by operating an operational shaft which is arranged inside the plunger; and when the operational ring is rotated to two different positions to allow the cavity of the valve seat to be communicated with the feed port and the discharge port respectively. Based on the reciprocating movement of the plunger, the volume and the pressure of the cavity of the valve seat are changed, thereby realizing the beverage filling. The invention has special processing technique and avoids the use of sealants in the valve, and is particularly suitable for filling fluid materials with high viscosity and difficulty in flowing under the action of self gravity. The filling process is clean and sanitary, the filling structure is simple, and the filling accuracy is improved. The invention is particularly suitable for the two-stage filling process of pulp beverages.

Description

1. Technical field [0001] The invention relates to a mechanical filling valve for fluid packaging, in particular to a quantitative filling valve for pulp-containing beverages. 2. Background technology [0002] With the continuous improvement of people's living standards, higher requirements have been put forward for the quality of life, and beverage products have been introduced accordingly. Fruit juice beverages have gradually replaced carbonated beverages because of their good taste and rich nutrition. In recent years, various beverage manufacturers have launched fruit juice beverages containing pulp respectively, which are very popular among consumers. The shape of the pulp in fruit juice beverages containing pulp is fibrous, granular and lumpy, the pulp is suspended in the juice, and the final product is a solid-liquid mixture, which is different from the previous pure liquid in terms of physical form. Drinks make a huge difference. Therefore, the filling of this type ...

AI Technical Summary

Problems solved by technology

[0008] 1. When quantitative filling is indirectly realized by equal liquid level filling, due to the volume error of the filling container itself, the actual filling volume error is relatively large after equal liquid level filling, and quantitative filling in the true sense has not been realized. packaging, cannot meet the requirements of commodity calibration, and does not meet the requirements stipulated in the Product Measurement Law and the "Measurement Supervision and Administration of Quantitatively Packaged Commodities";

[0009] 2. Using the principle of gravity filling, it is difficult to fill viscous fluids;

[0010] 3. It is not possible to fill fluids containing particles or massive suspended matter. As mentioned above: the opening and closing valves of various filling valves are sealed with gaskets. The existence of solid pulp will destroy the sealing effect of the gaskets. The reliability of the opening and closing of the valve cannot be guaranteed; at the same time, the mixture of pulp and juice is easy to block the return air pipe and cause the liquid level to be inaccurate;

[0011] 4. There is a filling device installed in the filling tank. The device is soaked in the material, which is not easy to clean, and it will stir the material during operation, which is not conducive to filling.
