Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention This invention relates to a rotary pine serge machine for processing raw meat blocks such as everloin ham, boneless ham, and pressed ham.

Conventional technology After injecting pickling liquid into the raw meat loaves as described above for flavoring and preservation, they are subjected to a pine surge treatment to soften the meat loaves and at the same time to ensure that the injected pickling liquid permeates uniformly throughout the meat loaves. Ru. This process is generally carried out by rotating a tank containing raw meat blocks for a certain period of time.

As described above, the pine surge equipment consists of a cylindrical tank with transportation wheels at the bottom, an opening at the top that can be opened and closed with a lid, and a cylindrical tank that is rotatable around a horizontal axis relative to the mount.
a support frame that supports the tank and rotates it from an upright state to a sideways state; A rotary pine surge machine equipped with a rotatably supported drive roller and a drive device that rotates the drive roller is known (Japanese Patent Publication No. 55-3929).
(See Publication No. 7).

Problems to be Solved by the Invention When the raw material meat is subjected to pine surge processing using the above-mentioned rotary pine surge machine, the tank containing the raw material meat is supported horizontally on a support frame and rotated, so that the upper opening of the tank is rotated. It is sealed with a lid, and there are two types of lids: one is to attach it to each tank individually like the device disclosed in the above-mentioned patent publication, and the other is to attach a common lid by lifting it to the top of the support frame. There are two methods.

The latter device, in which the lid is attached to the top of the support frame, does not require a lid to be attached to each tank like the former, so it is advantageous both economically and in terms of handling. The increased height may make installation difficult in some locations, and the tank may be
It's more than a meter high, and it's more than an o meter, so
There were problems such as opening and closing the lid was not easy for women and short workers. Moreover, as the amount of processing increases,
As tanks tend to become larger, the above-mentioned problems have become important technical issues for this type of rotary pine surge machine.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a tank lid opening/closing device which limits the increase in the height of the support frame as much as possible and facilitates the opening/closing operation of the lid.
