  • Patent number: 6033301
    Abstract: A fan filter unit is provided for use in filtering air circulating in a clean room. The fan filter unit includes a unit casing; a ventilation fan housed in the unit casing; a dust removal filter in the bottom of the unit casing; and one or more gas absorption filters for removing gases from the circulating air. The one or more gas absorption filters are located in the unit casing such that the ventilation fan can be inspected without removing the one or more gas absorption filters and an inspector can walk on an upper face of the unit casing. In one preferred embodiment, the one or more gas absorption filters are located above the dust removal filter and below the ventilation fan. In a second preferred embodiment, a fan filter unit is provided that includes a plurality of fan filter subunits, each fan filter subunit comprising a unit casing, a ventilation fan housed in the unit casing, and a dust removal filter in the bottom of the unit casing.

  • Patent number: 6020014
    Abstract: The present invention provides a processed fat and oil composition comprising (1) fat and oil, (2) a polyglycerol saturated fatty acid ester having an average degree of esterification of 40% or higher, wherein at least 70% by weight of the fatty-acid moieties are derived from a saturated fatty acid, and (3) an unsaturated fatty acid ester, wherein at least 60% by weight of the fatty-acid moieties are derived from an unsaturated fatty acid. The processed fat and oil composition is used as a processed fat and oil composition for foods, particularly, for producing baked confectionery containing an egg component.

  • Patent number: 5897906
    Abstract: The present invention relates to an oil and fat composition for frying comprising: (A) an oil and fat having a solid fat content of 3 to 20% by weight at 20.degree.C., and (B) a polyglycerin fatty acid ester of 0.01 to 5% by weight based on the total weight of (A) and (B), which has not less than 75% of a degree of esterification thereof and has not less than 90% by weight of the constituting fatty acid of the polyglycerin fatty acid ester which satisfy the following definitions (1) to (3): (1) the content of the saturated fatty acid having 8 to 12 carbon atoms being 10 to 55% by weight; (2) the content of the saturated fatty acid having 14 to 22 carbon atoms being 40 to 80% by weight; and (3) the content of the unsaturated fatty acid having 16 to 22 carbon atoms being 5 to 20% by weight.

  • Patent number: 4895732
    Abstract: A chocolate comprising a hard butter and a sucrose fatty acid ester, wherein said hard butter is a nontempering type and said sucrose fatty acid ester comprises capric acid, lauric acid or myristic acid as a constituting fatty acid and has an average degree of substitution of the fatty acid to the sucrose of 4 to 7, is disclosed. This chocolate scarcely suffers from any fat bloom upon storage and thus is highly preferable.
