Abstract

PURPOSE:To suppress the damage of a meat paste product and the lowering of the quality caused by void-formation, effectively, by carrying out the primary heating process effective at relatively low temperature and pressure in a forming tube and the secondary heating process necessitating high temperature on a conveyor. CONSTITUTION:The raw material of meat paste is supplied continuously with the pump 1 to the forming apparatus 2 furnished with a forming tube 2b having modified cross-section and with a magnetron 2c to heat the meat paste raw material in the forming tube at a temperature higher than the gel-initiation temperature. The secondary heating apparatus 3 is furnished with a belt conveyor 3b to transport the material formed by the forming apparatus 2 and delivered continuously from the apparatus and with a heating means 3d to heat the material on the conveyor at a temperature higher than the primary heating temperature. As a result, the damage of a meat paste product and the lowering of the quality caused by void-formation can be suppressed effectively, and the length of the forming tube can be shortened to enable the transfer of the raw material under low pressure even in the case of using a pipe having modified cross-section.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for producing paste products, such as livestock paste products such as Wiener sausages, and seafood paste products such as kamaboko.

[Prior art]

Conventionally, the manufacturing method and equipment for this kind of paste product are as follows:
A method and an apparatus for continuously forming a dough product by irradiating the dough material with microwaves during the process of pumping it through a forming tube using a meat pump, heating and shaping the dough material, and then cooling it further. has been proposed (Jikko Sho 56-517
No. 51).

[Problem that the invention seeks to solve]

However, in the conventional method and apparatus as described above, the minced material is heated and pumped inside the forming tube, so cavities are likely to be formed due to the air expanded during the heating process, and when it leaves the forming tube, When the external pressure is released, the trapped air expands and breaks through the molded product and flows out, often damaging the product.Furthermore, the dough material is molded and aged as it moves through the molding tube. As a result, the molded tube becomes longer, and the meat pump pressure must be increased correspondingly, resulting in lower production efficiency and problems such as difficulty in cleaning, especially when an irregularly shaped molded tube is used.

[Means for solving problems]

The present invention has been made in view of the above circumstances, and its purpose is to perform heat treatment on the dough material in a primary heating process in which the dough material is shaped and solidified, and a second process in which the molded and solidified material is further heated at a high temperature. Separated from the secondary heating process, the primary heating process, which requires relatively low temperature and low pressure, is carried out inside the forming tube, while the secondary heating process, which requires high temperatures, is carried out on a conveyor without using the forming tube, which may damage the product. Not only can quality deterioration due to the formation of cavities be effectively suppressed, but even when the dimensions of the formed tube are shortened and a deformed pipe is used, it is possible to perform pressure feeding at low pressure, and it can also be used as a secondary heating means. An object of the present invention is to provide a method for manufacturing a paste product and an apparatus therefor, in which the primary heating time is shortened by increasing the microwave output, and the overall production efficiency can be improved.

The method for producing a dough product according to the present invention includes a step of heating the dough material to a gelling temperature or higher using microwaves while pumping it through a molding tube with an irregular cross section, and a step of continuously feeding the dough material from the molding tube (forming The method is characterized in that it includes a step of secondary heating the material for a required period of time while transporting the material on a conveyor.

The temperature at each outlet of the secondary heater 3 was heated to the gelation start temperature and the secondary heating temperature, respectively, and the product did not lose its shape, and there were hardly any cavities caused by air bubbles or damage to the appearance. The microwave output was set to 14 because both the molder outlet temperature and the secondary heater outlet temperature were slightly higher than the reference temperature, so the output of the variable magnetron placed in the molder 2 was adjusted. Alternatively, it is desirable to reduce each temperature by adjusting the pump output and adjusting the moving speed of the dough material.

〔effect〕

As described above, in the method and apparatus of the present invention, the dough material is heat-treated in two steps: primary heating and secondary heating. Since the material is heated above the temperature at which it starts to form, and the secondary heating is performed under atmospheric pressure without using a forming tube, the dough material can be heated and formed to the extent that it does not lose its shape. Moreover, even if the bubbles contained within expand, they can be directly discharged to the outside, creating a cavity in the product and preventing the product from being damaged by the bursting of the bubbles.Furthermore, the molded tube itself is Since it is short, the pressure of the pump can be small, and cleaning is easy even when using an irregularly shaped tube as a forming tube.Furthermore, heating time can be shortened by increasing the microwave output in the secondary heating process. The present invention has excellent effects such as greatly improving manufacturing efficiency.
