DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for packing a ham into a casing and sealing and packaging the ham. The present invention relates to a pretreatment device suitable for shaping into a raw material, that is, a raw material shaping device for ham products.

[0002]

2. Description of the Related Art A ham product is different from other meat secondary products in that a series of meat treatments are performed while raw meat remains in a mass state, and the distribution of meat quality and fiber arrangement are almost the same as those of raw meat. Have maintained. Therefore, in a state where the meat mass is hermetically sealed in a casing, the cross-sectional shape of the ham product may return to the cross-sectional shape of the raw meat mass. In particular, ham products filled in long casings for producing sliced ham have a strong tendency.

[0003] In order to avoid such a problem, the raw meat block is pre-processed before packaging, and this kind of pre-processing apparatus is known, for example, from JP-A-1-193194. However,
This device performs pretreatment for automatic packaging of relatively short ham products. There, a saucer having a groove with a semicircular cross section and a cover are formed into a cylindrical shape by compressing the raw meat mass vertically, and extruding it with an operating cylinder and cutting it at predetermined lengths. . That is, the raw meat mass having a non-circular cross section such as a cocoon shape is compressed and deformed into a columnar shape, thereby facilitating the filling of the casing.

[0004] In order to produce long-sized ham products for sliced ham, a different processing procedure is used from the above-mentioned pretreatment. The raw meat mass is filled into the casing by a filling device or an automatic packaging device. Then, the semi-packed body taken out of the filling device is transferred to a shaping device, and the meat mass is beaten from the outer surface of the casing to loosen the meat fibers, thereby removing the shape restoring force (literature unknown). In the shaping apparatus, the raw meat mass is held in a vertically long sectional posture, the meat mass is beaten with a hammer from the upper surface side to loosen the meat fiber along the longitudinal direction of the meat mass, and the meat fiber is similarly turned upside down. Is relaxing.

[0005]

In the above-mentioned pretreatment mode, after filling the casing with a meat lump, the lump is transferred to a shaping device to remove the shape restoring force, and furthermore, converging portions at both ends of the casing are sealed by a sealing device. It is necessary to seal and fix the ham with a clip, and a lot of manpower is required for a series of ham packaging operations, and there is a dissatisfaction that the packaging operation cannot be performed efficiently. In particular, when meat fibers are beaten and loosened, the meat mass must be beaten separately on the upper surface side and the lower surface side, and the processing requires time and effort.

SUMMARY OF THE INVENTION It is an object of the present invention to perform a shaping process for removing a shape restoring force before filling a casing, and to complete the shaping process in one raw material feeding operation. An object of the present invention is to obtain a raw material shaping apparatus that can efficiently perform the above-mentioned operations without requiring any manual operation. Another object of the present invention is to provide a raw material shaping apparatus suitable for rapidly performing a series of packaging operations from pretreatment to hermetically sealed packaging by a casing.

[0007]

A raw material shaping apparatus according to the present invention comprises: a raw material feeding unit 1 for feeding a raw material mass M having a cylindrical shape; and a meat mass fed from the raw material feeding unit 1. And a shaping unit 2 for removing the shape restoring force by hitting

And an adjusting end plug 28 that enters the holder 27 and regulates the cut length of the meat mass.

[0008]

In the operating state, the meat chunk fed from the raw material feeding section 1 is moved while passing through the rubber tube 10 by the hammer 1.
It is beaten with 1 and the meat fiber is loosened. At this time, the hammers 11 are opposed to each other with the rubber tube 10 interposed therebetween, and furthermore, at least two pairs of hammers 11 are used to continuously beat the meat mass fed and moved, so that the meat fibers of the raw meat mass M are evenly loosened. be able to. When the pre-processing device 3 is provided continuously in the shaping section 2, the meat mass can be re-formed into a cylindrical shape and cut into a predetermined size continuously in the shaping process. Processing can be performed collectively.

[0009]

According to the present invention, the raw meat mass M is beaten to loosen the meat fibers by feeding the raw meat mass M into the rubber tube 10 while at least two pairs of opposing hammers 11 are interposed through the tube wall. And beat the chunks of meat. Therefore, according to the raw material shaping apparatus according to the present invention, it is not necessary to temporarily fill the casing with the raw meat mass M in order to perform the shaping process, and the work and time for transferring the filling work and the filled half-packed body are not required. Can be omitted. Furthermore, since the raw meat mass M can be beaten with a plurality of hammers 11 to loosen the meat fibers evenly while the raw meat mass M passes through the rubber tube 10, the raw meat mass M can be reduced as compared with the conventional shaping apparatus. Can be efficiently performed without human intervention.
