30546 results about "Food science" patented technology

Food science is the science of nature devoted to the study of food; it is often confused with "food technology". The Institute of Food Technology defines food science as "the discipline in which the engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public". The textbook Food Science defines food science in simpler terms as "the application of basic sciences and engineering to study the physical, chemical, and biochemical nature of foods and the principles of food processing".

Beverage dispenser having selectable temperature

The present invention dispenses hot coffee or other beverage by the cup at a selected temperature, which can be varied from cup-to-cup. The beverage is brewed in a conventional way, and in one embodiment is stored in a conventional holding tank at elevated temperature. The holding tank communicates with two smaller reservoirs. A quantity of beverage is stored in a first reservoir at an elevated temperature, at or above the maximum desired dispensing temperature. A second quantity of beverage is cooled and stored in a second reservoir at a lower temperature, at or below the minimum desired dispensing temperature. When a cup of beverage is to be dispensed, the temperature is selected, and a quantity of beverage is dispensed from each of the reservoirs, proportioned so that the resulting dispensed beverage is at the selected temperature. In another embodiment, the first reservoir is omitted, and beverage from the holding tank provides the elevated temperature beverage for mixing. In several other embodiments, no cooling mechanism is needed. Instead, the holding tank is at a cooler temperature than the lowest vend temperature, and the beverage must be heated to the hot reservoir temperature and, in one embodiment, the cold reservoir temperature. In another embodiment, the holding tank functions as a cold reservoir. In still another embodiment requiring no heaters, the holding tank is eliminated, and the beverage is held in insulated chambers at the higher and lower temperatures.

Chlorinated polrvinyl chloride modified material as well as preparation method and application thereof

The invention relates to a chlorinated polrvinyl chloride modified material as well as a preparation method and application thereof. The raw material formula of the chlorinated polrvinyl chloride modified material comprises the following components in parts by weight: 40-90 parts of chlorinated polrvinyl chloride, 20-70 parts of polrvinyl chloride, 5-30 parts of modified resin, 1.5-10 parts of heat stabilizing agent, 20-60 parts of plasticizer, 1-10 parts of antioxidant, 1-10 parts of lubricating agent, 5-40 parts of filling agent, 8-40 parts of fire retardant, 8-40 parts of flame retardant synergist and 1-20 parts of polrvinyl chloride processing aid. Compared with the known CPVC (chlorinated polrvinyl chloride) modified plastic, the CPVC modified plastic disclosed by the invention is more excellent in physical and mechanical properties and is relatively reduced in cost; and compared with the known CPVC modified plastic, the CPVC modified material disclosed by the invention is obviously improved in heat resistance and flame retardant property (oxygen index can reach about 45%, and simple root of CPVC modified material can be vertically burnt) besides more excellent processabilityand obviously improved material brittleness and shock resistance. Thus, the CPVC modified material disclosed by the invention is suitable for being used as a wire and cable sheath material.
