Abstract

PURPOSE:To efficiently regenerate a seasoning liquid for pickling without causing the degradation of the seasoning and the deterioration of the delicious taste component of vegetables in the pickling seasoning liquid by roughly filtering the used seasoning liquid for pickling and subjecting the liquid to fine- filtration to eliminate bacteria. CONSTITUTION:Used seasoning liquid for pickling is roughly filtered with a coarse filter 11, filtered with a preparatory filter 21 for the bacteria elimination and finely filtered with a bacteria elimination apparatus 31 composed of a fine filter 33 having a pore size of <=0.2mum to effect the elimination of bacteria and regenerate the pickling seasoning liquid.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reclaiming used pickle seasoning liquid after pickling pickles.

[0002]

2. Description of the Related Art Conventionally, used pickle seasoning liquid is sterilized by heating and reused again as a pickling liquid for pickles, a dipping liquid for pickles at the time of sale, and the like. However, when it is markedly colored, it is difficult to use it as a pickling liquid for pickles, a dipping liquid for sale, etc., and the used pickling seasoning liquid is discarded as it is in rivers and the like.

[0003]

Since the used pickled seasoning liquid is originally a food seasoning liquid, it contains no harmful substances. However, in the above conventional treatment method, since it is heat-sterilized, when the used pickle seasoning liquid is reused as pickling liquid for pickling, dipping liquid at the time of sale, the flavor of the vegetable material is lost, and the seasoning is deteriorated. Raise it. Also, if spores of bacteria are formed by heat treatment at 100 ° C, the spores of the bacteria may not be completely killed, and even if spores are not formed, they survive in a boiling hot spring. As the confirmed fungi were confirmed, the heat-resistant bacteria could not be removed, and the sterilization was insufficient. In addition, when a large amount of waste is discarded, the salinity, BOD, etc. of the river may be temporarily increased, which may adversely affect the ecosystem of the river.

[0004]

[Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides a method for regenerating a pickle seasoning liquid, which comprises roughly filtering a used pickle seasoning liquid and then finely filtering to remove bacteria. It is provided.

[0005]

In the present invention, the used pickled seasoning liquid is first roughly filtered by the rough filter (11) in order to prevent the filter material (13) from being clogged early during the fine filtration. The used pickled seasoning liquid that has been roughly filtered is then sterilized by the fine filter material (33) to complete the regeneration.

[0006]

EXAMPLES The present invention will be described with reference to an example shown in FIG. 1. The steps of the method for reclaiming used pickled seasoning liquid are as follows: coarse filter (11), disinfection pre-filtration device (21) and disinfection. It is implemented by the reproduction processing device (1) including the device (31). The coarse filter (11) is constructed by stacking filter media (13) consisting of a filter frame (14A) and a filter cloth (14B) in multiple stages, and arranging the stay boards (16A), (16B) at the top and bottom, and fixing columns (17 ) Is inserted through the nut (18) and the filter material (13) is sandwiched and fixed between the stayboards (16A) and (16B), and the used pickle seasoning liquid is introduced. The used pickled seasoning liquid introduced into the coarse filter (11) from the mouth (12) and roughly filtered flows out from the outlet (15). In the rough filter (11), the number of used filter media (13) is changed according to the amount of the used pickle seasoning liquid and stacked. The disinfection pre-filtration device (21) is a cylindrical main disinfection pre-filtration material (23) in which a tank body (22) and a cotton thread installed in the tank body (22) are multiply wound.
And an inlet (24) for the used pickled seasoning liquid that communicates with the tank body (21) and an outlet (25) for the used pickled seasoning liquid that has been prefiltered for sterilization. Note that the disinfection pre-filtration device (21) is not used when the used pickled seasoning liquid is roughly and sufficiently filtered. The disinfection device (31) includes a tank body (35) and the tank body.
A cylindrical fine filter material (33) consisting of a hollow fiber membrane (33) installed in (35), an inlet (32) and a filtration port for the used pickle seasoning liquid that communicates with the tank body (35). , The outlet (34) of the used seasoning liquid that has been sterilized.

In addition to the above-mentioned structure, the coarse filter has a filter medium (13).
Alternatively, a structure using a filter paper, a sand layer or the like may be used. As the fine filter medium (33), a plastic foam having fine continuous pores, a ceramic porous body, or the like may be used.

In the regeneration treatment device (1) having the above-mentioned structure, first, an appropriate amount of the used pickle seasoning liquid to be treated is sampled and diatomaceous earth is dispersed therein, and the pump (2) is used to introduce the seasoning liquid introducing pipe (3). Through the coarse filter (11), the coarse filter (11)
Precoat the filter cloth (14B) of the filter material (13). After the pre-coating, the pickled seasoning liquid is coarsely filtered by a pump (2).
The used pickled seasoning liquid introduced into (11) and introduced into the coarse filter (11) is precoated as described above, and the filter cloth of the filter medium (13) in the coarse filter (11) Coarse filtration is performed as it passes through (14B). When the seasoning liquid is deeply colored, the activated carbon is dispersed prior to the rough filtration and left for several hours for decolorization. The activated carbon is removed during coarse filtration. The used pickled seasoning liquid roughly filtered in this way passes through the seasoning liquid introduction pipe (4) from the crude filtered liquid outlet (15) to the inlet (24) of the disinfection preliminary filtration device (21). Sent. As described above, when it is not necessary to perform the disinfection pre-filtration, the disinfection pre-filtration device (2
The step of disinfection pre-filtration by 1) is omitted, and the used pickled seasoning liquid is fed from the outlet (15) of the coarse filter (11) to the seasoning liquid introduction pipe.
(3) through the inlet (32) of the disinfection device (31)
Directly introduced in 1). In the above disinfection pre-filtration step, 1 to
Fine solids of about 4 μm are removed by filtration. The used pickled seasoning liquid introduced into the sterilization preliminary filtration device (21) is the sterilization preliminary filtration material (2) installed in the sterilization preliminary filtration device (21).
Disinfection pre-filtered by passing through 3) Outlet (25)
Through the seasoning liquid inlet pipe (5) to the inlet (3) of the disinfection device (31).
It is introduced into the disinfection device (31) from 2). The used pickled seasoning liquid introduced into the sterilization device (31) after sterilization preliminary filtration passes through the fine filter medium (33) to filter and sterilize impurities such as yeast, bacteria, spores, etc. Recovered from the exit (34).

The pore size of the fine filter medium (33) may be selected according to the size of the target substance to be filtered and sterilized.
Generally, the minimum size of bacteria is about 0.2 μm, so that the pore size is preferably 0.2 μm or less.

[0010]

Therefore, in the present invention, the used pickled seasoning liquid is completely sterilized, and the used pickled seasoning liquid can be regenerated as a pickled liquid for pickling, a dipping liquid at the time of sale, and the like. This makes it possible to effectively use resources and reduce the load of drainage treatment.
