Abstract

PURPOSE:To accomplish the process simplification for fermentation by saccharification through such processes that the first tank is charged with raw materials followed by transferring the materials into plural tanks arranged in parallel, and the materials are left to stay for a specified time in each of the tanks, thereby producing saccharified unrefined soy in a simple manner. CONSTITUTION:Raw materials heat-treated in a boiler 131 are transferred through a pump 121 into a tank 101. Powdery sub-materials in vessels 112-117 and liquid sub-materials in a vessel 111 are also fed into the tank 101, and the raw materials thus combined are agitated and held for a specified time, and then transferred, using a pump 123, into saccharification tanks 102-106 where the materials are held again for a specified time and saccharified, thus obtaining the objective saccharified unrefined soy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of Sanryo 1.] The present invention relates to the fermentation of raw materials, and particularly to a saccharification and fermentation method that can be effectively applied to the fermentation method of raw materials for vinegar.

[Conventional technology]

] In vinegar production, grains are used as raw materials, and in order to make sukekamomi by adding koji, water, and other secondary ingredients, these n; CLl are necessary.
Because it takes one to several days to retain the raw materials and auxiliary materials in one tank, multiple tanks are prepared for that number of days, and raw materials and auxiliary materials are charged into each batch at staggered dates and times. This is to avoid having to prepare a large amount of saccharified moromi at once, which would require waiting time for the subsequent process, and to maintain uniform quality.

The conventional fermentation process will be explained with reference to FIG.

After the raw materials are processed in the steamer 231, they are transferred to fermentation and saccharification tanks (hereinafter referred to as saccharification tanks) 201 to 20 by the pump 221.
6. At this time, the viscosifying tanks 201 to 206 are selected by operating the switching valves 261 to 265. Similarly, powdered auxiliary raw materials in containers 212 to 217 are fed by gravity through container 234, and liquid materials in container 211 are supplied by pump 222 to saccharification tanks 201 to 206 into which the raw materials have been introduced. In this case as well, the saccharification tank is selected by operating the switching valves 241-245 and 251-255.

After adding the raw materials and auxiliary raw materials, these raw materials are uniformly stirred by the stirrers 271 to 276, and then approximately 1 to 7
It is saccharified and fermented for several days.

The above operations are performed sequentially for the saccharification tanks 201 to 206 at different dates and times. The raw material 4 that has undergone saccharification and fermentation, that is, the saccharified mash, is sent to the next step by the pump 223.

[Problem to be solved by the invention]

In the conventional method, raw materials and auxiliary raw materials are directly supplied to each saccharification tank, which complicates piping for tank selection and also complicates control systems such as valve switching.

Furthermore, since one tank covers all of the saccharification and fermentation processes for the raw materials, each tank needed to have its own heating and cooling functions if it was necessary to raise or cool the temperature as the saccharification and fermentation process progressed.

In view of the above technology, the present invention aims to provide a saccharification and fermentation method that can greatly simplify the supply piping for raw materials and auxiliary raw materials and the discharging piping for the saccharified mash, as well as simplifying the control means. It is something.

[Means to solve the problem]

In the present invention, when raw materials are saccharified and fermented, the raw materials are received in a first tank, and then the contents are transferred to multiple tanks arranged in parallel, and the contents are left in each tank for a certain period of time before being processed into saccharification and fermentation. This is a saccharification and fermentation method designed to obtain

[Effect]

Traditionally, everything from preparation to fermentation and aging was done in the same tank, but by having each tank share the input of raw materials and auxiliary materials, as well as saccharification and fermentation, a stirrer was required in all tanks) 11! In addition, the accessories and piping for each tank can be significantly reduced, such as by attaching the raw material and auxiliary raw material supply piping only to the first tank, and the saccharification and fermentation process as a whole is streamlined.

〔Example〕

An embodiment of the saccharification and fermentation method of the present invention will be explained with reference to FIG.

The raw material is heat-treated in the steamer 131 and then transported to the saccharification tank 101 by the pump 121.

Similarly, containers 112-11? The powdered auxiliary raw material inside passes through the container 134 by gravity, and the liquid material in the container 111 is supplied to the saccharification tank +01 by the pump 122.

The raw material and the auxiliary raw material are stirred by stirring 181 and held for a certain period of time. Thereafter, it is transported to the saccharification tanks 102 to 106 by the pump 123. At this time, switching valve 1
/ll-144, the saccharification tank 10
Select 2 to 106. The raw material that has been saccharified, that is, the saccharified moromi, passes through the switching valve 151 to +5/l to the pump 12.
4, it is sent to the next process.

〔Effect of the invention〕

By the method according to the present invention, the transportation system for raw materials and auxiliary raw materials can be simplified without impairing the functions in the saccharification and fermentation process. In addition, the temperature raising, cooling, and stirring functions are only required for several hours after the addition of the auxiliary materials, and after that, the temperature can only be increased in the tank into which the auxiliary materials are input. Since there is no need to provide a cooling and stirring device, only the first tank requires a stirring device, temperature raising device, and cooling device, making it easier to clean the tank and reducing costs.
