  • Patent number: 6234066
    Abstract: A method and rotary blancher for processing food product using a heat transfer medium and directed flows of a fluid that can comprise a liquid, a gas, a vapor or a combination thereof. The directed flows can be discharged from orifices or banks of orifices that are distributed around the food products in the blancher. The flows are discharged at a high flow rate, a high pressure, or a combination of both. Where a liquid is discharged, it preferably is discharged at a flow rate of at least 20 gpm and at least 30 psi. Where a gas is discharged, it is discharged at a flow rate of at least 60 CFM at a pressure of at least 2 psi or at a flow rate of at least 10 CFM at a pressure of at least 80 psi. If desired, discharged fluid can be recirculated to save energy. To help increase agitation and help break up clumps of food products in the blancher, direct-contact mechanical agitation devices, such as baffles, can be used.

  • Patent number: 6205913
    Abstract: A rotary blancher that is substantially sealed during operation to increase food product heating speed and efficiency. The blancher has a sealed housing, a novel substantially sealed food product inlet, and a novel substantially sealed food product outlet. A heat transfer medium, such as water or only steam, is introduced into the blancher to heat the food product inside the blancher. During operation, food products are substantially continuously introduced into the blancher through the food product inlet, processed by the blancher, and thereafter discharged from the blancher through the food product outlet. As a result, a greater amount of food products can be more quickly heated to a desired temperature using a blancher of this invention as compared to a blancher that is not sealed.

  • Patent number: 6189440
    Abstract: A self-contained, continuous flow pasteurizer is herein disclosed. Such a pasteurizer comprises a first tank and a second tank interconnected by a pasteurization conduit. A single pump pumps fluids from the first tank to the second tank at a predetermined flow rate. Fluids are heated to their desired pasteurization temperature in a first section of the conduit and are held at this temperature while flowing through a second section of the conduit. Fluids not reaching the desired pasteurization temperature do not pass into the second section of the conduit but are recirculated back to the first tank by a recirculation valve and conduit connected between the first tank and the pasteurization conduit. A third section of the conduit passes through a cooling structure so that the fluid flowing in the conduit will be cooled down from its pasteurization temperature before being deposited in the second tank.

  • Patent number: 5846583
    Abstract: A method and system are provided for pasteurizing a fluid product. Heated fluid product flows through a passageway to a directional flow valve for directing the heated fluid product through either a primary flow path or a divert flow path. A temperature sensor senses temperature of the heated fluid product at a location in the passageway spaced from the valve so that change in temperature of a portion of the heated fluid product is sensed before that portion of the heated fluid product flows to the valve. The valve directs flow of the heated fluid product from the passageway to the divert flow path when the sensed temperature is below a predetermined temperature for pasteurization of the fluid product, and continues to direct the flow to the diverting flow path at least until the sensed temperature is at or above the predetermined temperature for a predetermined period of time.

  • Patent number: 5722317
    Abstract: An aseptic food processing system including a non invasive temperature measurement apparatus capable of processing low acid particulate foods. A magnetic particle is inserted into a food particle in the aseptic system and undergoes heating corresponding to a cold zone in the food product being processed. After heating, the particle is passed by one or more magnetic sensors disposed about the food stream path. The magnetic particle magnetizes in proportion to its magnetic susceptibility as it passes magnets included in the sensors. The particle is chosen to be paramagnetic at processing temperature ranges, and produces a magnetization in a sensor coil in the sensor which is proportional to the magnetic susceptibility. Because the susceptibility varies with temperature, actual temperature measurements of cold zone heating within the food particles may be obtained.

  • Patent number: 5718164
    Abstract: An apparatus for roasting vegetable bulk material, in particular coffee beam is disclosed, in which essentially all of the cooling waste air of a cooler which cools the bulk material after the roasting operation is heated to roasting-gas temperature in a heat-exchanger stage and fed to the roaster. Essentially all of the roasting waste gases are heated, in a heating stage, to an extent which is necessary for increasing the temperature of the cooling gases to the roasting-gas temperature. Since the roaster operates with a higher roasting-gas throughput than hitherto, it is possible, with comparable roasting capacity, for the roasting-gas temperature to be reduced, this resulting in a more uniform roasting result. The apparatus has reduced harmful-substance emission along with increased thermal efficiency. Also disclosed is a method of roasting and cooling bulk material by utilizing the disclosed apparatus.
