  • Patent number: 6688214
    Abstract: In a production method for processed soybean food products that includes a grinding step (A) in which raw soybeans are ground to obtain a soybean slurry and a heating step (B) in which the obtained soybean slurry is heated and thermally denatured, a deaeration step (C) for removing air bubbles mixed in with the soybean slurry is performed partway through the heating step (B). These steps can be effectively performed using a soybean slurry thermal deaeration device 1 provided with a first heating apparatus 10 for raising the temperature of the soybean slurry to a predetermined intermediate temperature; a deaeration apparatus 20 and a second heating apparatus 30 for completing the thermal denaturation by further heating the soybean slurry once it has been deaerated in the deaeration apparatus 20.

The rate of malt movement through the drying zones is varied according to the moisture content of the malt at predetermined points in its travel whereby to achieve a desired drying rate and moisture content in the malt as it travels through the various drying zones. Sulfur dioxide gas is selectively infused with the air in the drying zones to minimize carcinogens within the malt. Optional treatments are provided for the malt as it passes through the drying zones, including subjecting the malt to a vacuum to facilitate moisture removal and to effect a sanitizing of the malt.

  • Patent number: 6070517
    Abstract: The present invention relates to a device for removing dampness form a cooking space (3) of a steam cooking device or a pressure cooker (1). The cooking space is at least partially filled with steam. The steam or the mixture of hot air and steam, respectively, is circulated in the cooking space (3) by means of a ventilating wheel (9) or a radial fan. The gas mixture to be circulated is sucked in substantially axially in the central area (10) of the ventilating wheel (9) and is drawn off to the outside substantially radially, with superfluous steam or superfluous mixture of hot air and steam, respectively, being removed from the cooking space (3) through a waste air opening (11) and dry fresh air being supplied from the outside for removing dampness. The dry fresh air is supplied at the rear, is sucked in through an opening (27) provided in the rear front end (25) of the ventilating wheel (9) and is deflected to the outside of the ventilating wheel (9) by way of a deflecting device (29).

  • Patent number: 6054165
    Abstract: The invention relates to a process and an apparatus for cooling high-viscosity sauces containing ingredients in the form of solid pieces. To develop a virtually continues process while preserving the ingredients in piece form as much as possible, according to the invention the following process steps are proposed:a) the sauce prepared at a temperature of 75.degree. to 120.degree. C. is pumped via a cooling system and is thereby cooled to a temperature of about 50.degree. to 55.degree. C.;b) the sauce pre-cooled in this way is pumped into a cooling tank under vacuum, which it passes through under the force of gravity, partly via enforced diversions and partly in free fall, the sauce being cooled by water evaporation to a temperature of about 3.degree. C. to 17.degree. C.

  • Patent number: 6044756
    Abstract: A vacuum pot capable of showing the vacuum status comprises a container and a cover body. The cover body comprises a seat, a top lid, an air-pumping unit, and an indicating unit. The top lid connects with the seat. A groove is installed on the top edge of the top lid. The air-pumping unit is installed between the seat and the top lid to draw out the air inside the container unidirectionally by the pressing and releasing of an air-pumping button. The indicating unit has a retractable pump. One end of the retractable pump connects with the seat. The retractable pump connects with the inside of the container. The other end of the retractable pump connects with a rack. The rack is meshed with a gear. The gear is pivotably installed on the seat. The gear fixedly joins a pointer installed in the groove of the top lid. A scale is installed on the groove. Thereby articles can be superposed on the cover body, the vacuum degree of the vacuum pot can be known exactly, and the user can operate using only one hand.

  • Patent number: 6040013
    Abstract: Pieces of meat are tumbled with a marinade in a tumbler that has a smoothly continuous surrounding side wall with no protrusions or baffles or other protrusions contacting the pieces of meat. The tumbler is rotated about the axis of the side wall and gas is pumped from the tumbler during the tumbling to maintain a reduced pressure. The gas may be pumped to maintain a lower reduced pressure for a first time interval and to permit a higher pressure, still below atmospheric pressure, for a second period of time during a rest period. These two pressure levels are alternated during the alternate tumbling and rest periods.

  • Patent number: 6019034
    Abstract: An apparatus is provided for improving the flavor of distilled liquor by applying a vacuum to remove volatile compounds. The apparatus allows a consumer to treat various kinds of liquor in differing quantities regardless of the size or shape of the liquor bottle. A pitcher serves as a receiving vessel for the liquor to be treated. The pitcher has a hollow handle which, in conjunction with a vacuum stand, allows air to be drawn through the hand and discharged into the liquor at the bottom of the pitcher. The vacuum stand is especially adapted to sealingly receive the pitcher and cause air to flow through the liquor. The pitcher is placed on the vacuum stand, a lid portion of the stand is placed over the pitcher to create a seal, and a vacuum is applied on the contents of the pitcher. Air is drawn through the hollow handle and percolates or bubbles out at the base of the pitcher, creating agitation of the liquor and causing removal of the volatile compounds.

  • Patent number: 5962061
    Abstract: Process and apparatus for the production of confectionary mass from the components of milk proteins, sugar, glucose, fat and water. The components are homogenized in a closed tank under controlled pressure and temperature and are transferred from the closed tank to a scraped surface rotor cooker at a pressure between 0.2 and 0.9 bar absolute. The components are retained in the cooker for a period of 4 to 10 seconds, then transferred from the cooker to an evaporation chamber that is in open connection with the cooker and that is at a pressure of 0.2 to 0.9 bar absolute. Steam from the evaporation chamber is condensed in a condenser connected to a vacuum chamber. The product is withdrawn from the vacuum chamber at a temperature below 100.degree. C. When little or no Maillard reaction is desired, the closed tank is maintained at a pressure no more than 1 bar absolute at a temperature between 40.degree. C. and 90.degree. C.
