Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for bleaching aquatic animal meat, and provides an apparatus for automatically bleaching aquatic animal meat.

In general, aquatic animal meat is extracted from its raw materials and then exposed to water in order to remove dirt, blood, fat, etc. mixed into the meat. Popular is a raw material for the surimi of aquatic animal meat used as a raw material for aquatic and livestock processing, and the basic manufacturing method is that the raw material is exposed to water as shown in Japanese Patent Publication No. 37-9257. In addition, in Japanese Patent Publication No. 58-1903.1904 by the same applicant as the present invention, salt is added to aquatic animal meat, kneaded to make minced meat, and the mixture is passed through a nozzle with pores to form a mixed aqueous solution of salt and acid. Fibrous foods are obtained by ejection spinning in an aqueous protein denaturing solution. Water exposure is then performed to remove excess protein denaturant aqueous solution.

As a device for such water bleaching, there are conventional water bleaching tanks, automatic fish meat bleaching machines, and the like.

However, in all of these conventional devices, the predetermined amount of bleaching water is not automatically and accurately injected and discharged.

In view of the above, the present invention can be incorporated into a fully automated seafood processing product production line, can continuously expose a large amount of aquaculture animal meat, and can adjust the H of the water used to expose the raw meat. The purpose of the present invention is to provide an automatic bleaching device for aquatic animal meat that can be accurately carried out.

A stirring blade and a rotation mechanism 32 for rotating the stirring shaft are provided on the protruding portion of the stirring shaft 30 from the tank wall. It has a chain 36 wound between driven sprockets 35 provided at the protruding end of the shaft 30.

A support plate 37 is fixed to the upper surface of the exposure tank 1 in the center in the longitudinal direction, and a jacking mechanism l is mounted on the support plate 37.
The structure 38 is attached. This jack [38 is for vertically moving a discharge pipe 39 for discharging water in the bleaching tank, and this discharge pipe 39 is used for discharging the water in the bleaching tank 1.
It is slidably engaged with a discharge pipe 40 that penetrates the bottom surface 1a of the tank and projects into the bleaching tank. The jacking mechanism 38
indicates a motor 41 and a drive shaft 42 rotated by this motor 41, and the upper part of the drive shaft 42 is a cover cylinder 42a.
The lower end of this drive shaft 42 is connected to the upper surface of the discharge tube 39 via a connecting frame 43, and the lower end of this drive shaft 42 is
has a funnel-shaped opening.

The discharge pipe 40 is a pedestal S as shown in FIG. It extends downward and connects to the discharge main 44, and this discharge main 4
Reference numeral 4 is for discharging the waste liquid to the outside after the exposure process is completed. A level meter 45 for measuring the water level in the water tank and raw meat, and a pH meter 46 for measuring H in the water tank are attached near the end of the support plate 37.

In addition, a level meter (not shown) is installed to supply the water level in each chamber 3a, 3b, 3c of the water tank 3, and to supply the neutralizing liquid from the neutralizing liquid tank 8 to each bleaching tank 1. A valve 8e is also attached to the base of each of the neutralizing liquid tubes. Furthermore, valves 9e are installed in each of the raw material feed branch pipes 9a, 9b, 9c, and 9d for sending the raw material after the bleaching process in the bleaching tank to the raw material feed main pipe 9 (1). There is.

Next, the operation of the present invention will be explained.

The aquatic animal meat to be processed is pushed up through the raw material supply pipe 24 by a vane pump (not shown) and supplied into the rotary screen 10. The rotary screen 10 rotates and is composed of a mesh, so water mixed with raw materials falls through the mesh and further passes through the mesh portion 11a formed at the lower part of the holding frame 11. The water falls into a water collection pan 50 provided below, and is sent into a drain pipe 51 installed at the bottom of this water collection pan 50.

The distribution device 2 initially faces the bleaching tank 1, into which a predetermined raw material is fed, and when the level of the raw material becomes constant (the level is detected by the level meter 45). As a result, the swinging mechanism of the distribution device 2 is operated, and the raw material is supplied to the next bleaching tank 1. In this way, the raw material is supplied to each bleaching tank 1 one after another.

When raw materials are put into the bleaching tank 1, the bleaching process is started. In this bleaching step, for example, a predetermined amount of water is supplied to one bleaching tank 1 from a chamber 3b located in the center of the water tank 3, and then a predetermined amount of water is supplied from the smallest chamber 3C of the water tank 3. Water is provided. After a predetermined amount of water is supplied to the bleaching tank 1, the stirring blade 3
1 is rotated to stir the raw material and water at the same time, and after stirring for a certain period of time, the rotation of this stirring blade is stopped and the raw material is allowed to settle. - After the raw material has settled, the jacking mechanism is activated and the drain pipe is lowered, and the drain port 39 of the drain pipe is lowered.
When a descends to a certain water level, tJl is emitted. After discharging a certain amount of clean water, the drain pipe 39 is raised again, and then a predetermined amount of water is supplied from the chamber 3a having a size intermediate to that of the water tank 3. 8
Neutralizing liquid is supplied from Furthermore, the stirring blade is operated to perform stirring again, and after a predetermined time has elapsed, the rotation of the stirring blade is stopped, and subsequently, the drain pipe 39 is lowered to drain the tap water. The settled raw meat passes through the raw material feed water pipe 9 and is sent to the next processing step.

In the middle of these steps, the level cutter 45 or pH meter 46 measures the water level in the tank or the pH in the tank.
H is constantly detected, and the supply of neutralizing liquid from the neutralizing liquid tank 8 and the supply of water from the water tank 3 are adjusted by these pH meters and level meters.

In the present invention, a predetermined amount of the raw material to be processed is automatically sent one after another to a plurality of bleaching tanks by a distribution device, and if the predetermined amount of raw material enters the bleaching tank and 1=, it is automatically transferred from the water tank 3. Water or, if necessary, the neutralizing liquid from the neutralizing liquid tank 8 is sent, and in this way the bleaching process is fully automated, and the raw meat that has undergone the bleaching process is automatically sent to the next processing process. It's getting wet.

The automatic bleaching apparatus for sea urchin and aquatic animal meat of the present invention as described above includes a plurality of bleaching tanks arranged in parallel, and a hook that can be swung horizontally to distribute the raw meat to these bleaching tanks. a water tank for storing water to be supplied to the 8 bleaching tank, a stirring blade for stirring the raw material in the bleaching tank, and a predetermined height for discharging the exposed water. This system consists of a device equipped with a drain pipe that can be moved to a vertical position, and can be incorporated into lines during the manufacturing process of various processed seafood products, making it possible to automate the line and reduce the amount of raw meat. The effect is that the processing labor is saved and the exposure TPi' can be performed accurately and quickly.
