［産業上の利用分野］
この発明は、料理に使用した食用油の油漉しに使用する
吸着剤に係り、特に業務用に使用される吸着剤として好
適な油漉し用吸着剤に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adsorbent used for straining edible oil used in cooking, and particularly to an adsorbent suitable for oil straining as an adsorbent used for commercial purposes. Regarding adsorbents.
［従来の技術］
てんぷらやフライ等の料理に使用された食用油を保存し

われている。[Conventional technology] When storing and reusing edible oil used for cooking tempura, fried food, etc., it is necessary to remove food debris such as fried eggs floating in the oil by filtering it while hot before storing. In particular, restaurants and factory cafeterias that use large amounts of cooking oil actively deodorize and decolorize it, and also use hot filtration to prevent cooking oil from oxidizing. In this case, diatomaceous earth and cristobalite are used as adsorbents for oil straining.
［発明が解決しようとする問題点］
しかしながら、前者の硅藻土を使用する場合には、濾紙

不足し、結局は濾過助剤として使用されているにすぎな
い。[Problems to be solved by the invention] However, when using the former type of diatomaceous earth, diatomaceous earth is spread over a filter paper, used cooking oil is poured on top of the filter paper, and the adsorbent is filtered by suction. Although the method using diatomaceous earth has excellent filtration performance, it lacks in terms of adsorption performance such as deodorization, decolorization, and peroxide removal, and in the end, the filtration It is only used as an auxiliary agent.

着性能を持たせるために油との接触時間を長くする必要
があることから、自然落下による濾過方式を採用してお
り、このために濾過速度が遅くて大量に処理する場合に
は処理時間が係り過ぎるという問題がある。In addition, when using the latter type of cristobalite, if the amount used is small, the deodorization and decolorization properties are poor, so a large amount of adsorbent, for example, about 9 to 3 in 20 adsorbent, is added to the cartridge. It is necessary to use it in a packed state, and there is a large loss of cooking oil captured by the adsorbent during filtration. In addition, since it is necessary to increase the contact time with the oil in order to provide adsorption performance, we use a filtration method that uses gravity drop. The problem is that it takes too much time.
従って、本発明の目的は、種々の吸着性能において優れ
た性能を発揮すると同時に、濾過性にも優れていて吸着
剤処理の際の作業性に優れ、特に業務用に適した油漉し
用吸着剤を提供することにある。Therefore, the object of the present invention is to provide an adsorbent for oil straining that exhibits excellent performance in various adsorption properties, has excellent filtration properties, and has excellent workability during adsorbent treatment, and is particularly suitable for commercial use. Our goal is to provide the following.

This is an adsorbent for oil straining consisting of 55% by weight and 1 to 5% by weight of bentonite.

中間的性質を示す。In the present invention, diatomaceous earth that has been conventionally used for oil straining can be used as is,
Further, as for attapulgite, activated alumina, and bentonite, conventionally known ones can be used as they are. These diatomaceous earth, attapulgite, activated alumina, and bentonite are all white or light-colored powders or granules, and their particle size is usually 1 to 500 μm, preferably 10 to 1 μm.
00 μm range is used. The above-mentioned gravel soil mainly functions as a filter aid, attapulshite is slightly inferior in deodorizing properties but is excellent in decolorizing properties, activated alumina is slightly inferior in decolorizing properties but excellent in deodorizing properties, and bentonite is a type of activated alumina that is superior in deodorizing properties. and exhibits intermediate properties of attapulgite.

-55% by weight, preferably 25-45% by weight, and attapulgite 15-55% by weight, preferably 25-45% by weight.
45% by weight, activated alumina is 15-55% by weight,
Preferably it is 25 to 45% by weight, and bentonite or 1
~5% by weight. The adsorbent for oil straining of the present invention can be changed as appropriate within the above range depending on the type of edible oil, particle size of the adsorbent, purpose of use, etc. However, if the diatomaceous earth content is less than 15% by weight, The filtration performance deteriorates, the filtration speed decreases, and the workability of adsorbent treatment deteriorates.On the other hand, if the amount exceeds 55% by weight, the filtration performance improves, but the adsorption performance such as deodorization and decolorization performance deteriorates. For attapulgite and activated alumina, if the amount used is less than 15% by weight, satisfactory performance in any of the adsorption properties cannot be obtained, and on the contrary, if it is more than 55% by weight, It becomes impossible to mix diatomaceous earth, attapulgite, and activated alumina in a well-balanced manner, causing problems in filterability and various adsorption performances.

Adsorption performance such as decolorization properties can be improved in a well-balanced manner.
