Description

[Detailed description of the invention] In the past, most of the sake lees used in sake brewing were used to make lees soup, pickles for vegetables, fish, etc., and for distillation of shochu, etc. However, due to changes in dietary habits, As a result, the demand for lees soup and lees pickles has become extremely low, and therefore sake lees must be disposed of as leftovers. On the other hand, the amount of sake lees used for shochu distillation is increasing, but the weight ratio of sake lees after distillation is 100%.
The amount has decreased by less than 1/2, and most of the water remains, and the sake lees after shochu distillation must also be disposed of.

By the way, these sake lees cannot be used as feed for livestock because they contain alcohol, and on the other hand, they cannot be used as fertilizer because they do not rot even if left in the natural environment. If it remains as it is for a long time, it will not be assimilated into the soil, and even if it is burnt with a burner, the surface will only become charcoal and the moisture inside will remain.

Another option is to spread it thinly and let it air dry for a long time and then burn it, but even small and medium-sized ordinary sake brewers can produce 40 to 50 liters of alcohol.
Since it produces a lot of sake lees, it requires hard labor and requires a large area of land, which has the disadvantage of significantly increasing the cost of sake production.

As described above, it is extremely difficult to process sake lees, so even if you request a processing company to treat it as industrial waste, there is currently no one to take it back.

The present invention was developed in view of the current extremely difficult situation in processing sake lees, and has been developed to accelerate drying by absorbing and dissipating moisture trapped in starchy molecules.
It is dried material that is made flammable so that it can be used as fuel.

First, mix sake lees (regardless of whether the shochu has been distilled or not) and newspaper torn into appropriate sizes, with a weight ratio of about 20.
The mixture is mixed in a kneader at a ratio of 1 to 1, and this mixture is broken into pebbles, rods, or uneven flat plates with a large surface area and easy to dry, and left in a drying room or room. It is designed to absorb and release moisture contained in it.

The newspaper to be mixed in may be torn into pieces of appropriate size, and it is better to mix the mixture so that it is not kneaded very well and leaves a suitable amount of paper pieces.

Newspaper is economically most suitable as a material to be mixed with, but other materials may be used as long as they are porous.

A good mixing ratio of sake lees and paper is 5:1 to 30:1 by weight. If the amount of paper is smaller than this, water absorption and dispersion properties cannot be expected, and if the amount of paper is larger than this, it is not economical.

Since the paper absorbs and releases the moisture from the sake lees, it was found that the mixture thus prepared dried sufficiently after being left indoors for about seven days, was easily ignited, and could be fully utilized as a fuel. It was also found that if it was burned together with heavy oil, etc., the entire product would burn even if the drying process was slow.

In addition, forced drying may be performed to speed up drying, and in this case, drying speeds up and it becomes possible to use it as a fuel.

Claims (1)

[Claims] 1. Forcibly mix sake lees and porous, highly absorbent paper pieces at a weight ratio of 5:1 to 30:1, and leave the mixture in a pebble-like, rod-like, or plate-like form that dries easily. Alternatively, a method for drying sake lees in which the moisture contained in the sake lees is absorbed and released through forced drying.
