JPS5945829A - Apparatus for sterilization and deodorization of emulsion drink - Google Patents

Abstract

PURPOSE:To sterilize and deodorize an emulsion drink without deterioration of the quality, by spraying the drink in a high-pressure steam atmosphere to effect the thermal sterilization, and then injecting into a vacuum chamber to effect the evaporation of water and deodorization. CONSTITUTION:The emulsion drink is sent to the infusion-type heating vessel 6 by the high-pressure pump 1, and sprayed from the top of the vessel 6 into the high-pressure steam filled in the vessel. The drink is heated and sterilized instantaneously by the process. The sterilized drink is then introduced into the heat- insulation pipe 11, maintained at a high temperature, and injected into the vacuum chamber 16 to decrease its temperature and at the same time, to evaporate the water and eliminate the odor developed by the heating. The sterilized and deodorized emulsion drink is sent to the next apparatus through the transfer pipe 24.

Description

[Detailed description of the invention] The present invention relates to an apparatus for sterilizing and deodorizing milky beverages.

In the production of milky beverages made from trusted seeds such as soybeans, the quality of sterilization technology that enhances the shelf life of the product has a major impact on the quality of the product, so various technological innovations have been made. Ultra-high temperature instant sterilization technology ([
IHT) is also used.

The present inventor has discovered that the present inventor has sterilized milky drinks made from seeds that are more easily burnt than milk, more likely to cause heat coagulation, more likely to increase viscosity and coagulate, and have many heat-resistant bacteria derived from the raw seeds. The present invention relates to a device that can sterilize and deodorize the milky beverages using ultra-high temperature instant sterilization technology without causing thermal coagulation or aggregation of proteins due to heat rise, and without imparting a heated odor. As a result of research, the present invention was achieved.

The present invention utilizes an in-seven system as a direct heating method to produce milky beverages from commercial seeds at ultra-high temperature (UHT).
It is an object of the present invention to provide a sterilizing and deodorizing device that sterilizes milky beverages and removes evaporation of moisture and odor added to milky beverages during the treatment.

The present invention provides a high-temperature sterilization and deodorization device for a continuous production device for milky beverages, which includes a pump that feeds milky beverages into high-temperature, high-pressure heating cans, a float meter that adjusts the flow rate of milky beverages from the pump, and a flow rate controller. An infuser-type high-temperature, high-pressure heating can connected to a line heater for preheating the milky beverage, a heat storage tube for retaining the milky beverage from the heating can, and a vacuum for vacuum evaporating the milky beverage from the heat storage tube. comprising a vacuum canister with a cyclone communicating with the device;
This is an apparatus for sterilizing and deodorizing milky beverages, which is characterized by sterilizing and deodorizing milky beverages without altering their quality.

The milky beverage to be sterilized and deodorized in the present invention means a vegetable milky beverage such as soybean milk, peanut milk, and cottonseed milk.

of The practical aspects of the present invention will be explained with reference to the drawings.

In the figure, 1 is a high-pressure pump that feeds the milky beverage (the flow path is indicated by an arrow) from a storage tank etc. to the infusion type heating can 6, and 2 is a high-pressure pump that adjusts the flow rate of the milky beverage from pump 1. 3 is a check valve, 4 is a line heater and preheater for the milky beverage from the pump 1, 5 is the top of the line heater 4 and the heating mortar 6 (milk beverage jetting head)
6 is an in-7 injection type high-pressure heating mill equipped with a liquid level gauge 1o;io on the front and a steam jet pipe (not shown) connected to the back, into which high-pressure steam is fed. A heating mortar that sprays milky beverage from the top while the milky beverage is being filled and instantaneously heats and sterilizes the milky beverage.
7 is a pressure gauge of the heating mortar 6, 8 is a safety valve of the heating mortar 6, and 9 is a pipe whose one end is connected to the bottom of the heating mortar 6 and the other end is connected to a heat retention pipe (holding pipe) 11. Piping with a temperature sensor installed near the bottom of 6,
Reference numeral 11 is a heat storage tube connected to the pipe 9, which is preferably kept several times longer than the heating temperature of the milk.
12 is a pressure regulator installed in a pipe 13; 13 is a Holden tube that is relatively longer than a heat storage tube used in milk sterilization; pipe to send,
14 is a reflux pipe, 16 is a vacuum evaporation of the milky beverage from the heat storage tube 11 to rapidly lower the temperature of the milky beverage, and evaporation of moisture added to the milky beverage as steam condensed water by heat treatment in a heating mortar 6. , vacuum cans for deodorizing heating odors, etc.
17 is a differential pressure gauge, 18 and 19 are upper and lower limit liquid level sensors, 20 is a bar gauge, 21 is a sanitary diaphragm valve, 22 is a line strainer, 123 is a sanitary pump, and 24 is sterilized and deodorized. A pipe for sending the milky beverage to a device for the next process, 25 an exhaust pipe, 26 a gas-liquid separator (cyclone) for exhausting air from the vacuum can 16, and 27 connecting the cyclone 26 to a vacuum device (not shown). A communicating pipe, 28, a solenoid valve provided in the pipe 27, 29
is the opening of the pipe 27, which is connected to the pipe communicating with the vacuum device; 30 is the circulation pipe; 31.32

According to the present invention, the pump 1 injects the milky beverage from the storage tank or the like into the high-pressure steam atmosphere filling the heat sterilization can (7) while adjusting the flow rate. , heat sterilization by spreading and dropping (for example, 1
40°C to 145°C), introduced into a heat storage tube and kept warm (for example, for about 60 seconds), and immediately squirted into a vacuum can to evaporate water added by heat treatment, deodorize, and rapidly cool. (for example, 75°C to 80°C), milky beverages can be heated instantly by heat treatment.
It absorbs the heat of condensation of steam, and at the same time adds water to itself and raises the temperature, so it can be heat sterilized without causing thermal coagulation or coagulation of proteins. Also, because the heat retention time is long, it can also sterilize heat-resistant bacteria. It is possible to deodorize heated odors and evaporate hydrolyzed water during heating without causing any significant changes in the protein structure when it is discharged into vacuum cans. It can be fed into a homogenizer.
