  • Patent number: 5403603
    Abstract: A control process and apparatus enable operation of a pressurized continuous cereal cooker and discharge auger with decreased steam utilization. An electric motor advances the cooked cereal mass through a pressurized zone comprising a quick-opening valve, preferably a butterfly valve. The current drawn by the electric motor is monitored to sense the accumulation of cooked cereal mass at the valve. A process signal, representative of the current drawn by the motor, is compared to a reference signal, representative of a selected value representative of a current higher than that required to turn an empty auger. A control signal based on the comparison of the first signal and the reference signal is then generated to open or close the valve in response to the control signal. When the process signal drops below the reference signal, the valve is closed.

  • Patent number: 5399367
    Abstract: A process and apparatus for cooking tortilla chips. Toast points on a baked tortilla chip are produced by a process whereby tortilla dough pieces cut to the shape of tortilla chips are placed on a stainless steel, open weave conveyor belt which passes through an electric oven whose temperature is controlled in the range of about 700 to 800 degrees Fahrenheit for about ten to twenty seconds, and thereafter baking the chips at a lower temperature for a longer period of time. By cutting the dough into chips prior to running them through the electric oven on an open weave conveyor belt, a random pattern of toast points is created.

  • Patent number: 5395633
    Abstract: An automatic cooking control method capable of cooking a food with a low moisture content at an optimum by utilizing a variation in output voltage of a humidity sensor. When a key signal corresponding to a food with a low moisture content is received, an initialization is performed. Then, the maximum voltage indicative of the maximum humidity is determined by reading the continuously increasing output voltage from the humidity sensor 10 times for 10 seconds. After the determination of the maximum voltage, a determination is made whether the output voltage has reached a sensing voltage corresponding to a voltage obtained by deducing, from the maximum voltage, a minute voltage varied depending on the kind of the food. The cooking operation is completed when the output voltage from the humidity sensor has reached the sensing voltage.

  • Patent number: 5392698
    Abstract: A method and apparatus for preparing essentially fat free chips such as potato chips and the like having an appearance and taste similar to conventional chips without the use of deep fat frying processes. The method of the present invention includes the steps of exposing sliced raw potatoes and the like to a high intensity microwave field that rapidly converts moisture within the slice into steam. These exposed slices are then dried by longer exposure to a lower energy microwave field. The apparatus of the present invention includes a meander waveguide with a microwave absorptive terminator at an end of the waveguide. Apertures are provided along portions of the waveguide for transporting the potato slices and the like through the waveguide. A belt link type conveyor belt having an open lattice structure is employed to convey raw product slices through the meander waveguide.

  • Patent number: 5391386
    Abstract: An apparatus for transferring multiple individual slices of a food product material from a food material supply source which includes a plurality of food product supply sources to a support substrate without substantially altering the predesignated pattern includes a rotating hollow drum disposed on and rotating around a stationary inner core member. The rotating member is disposed between a slicing blade in substrate, negative air pressure is applied to the rotating transfer member to cause individual material slices to adhere to the outer surface of the transfer member in the same pattern in which they are slices from the food supply and to leave the outer surface of the transfer member in the same pattern thereby permitting, in effect, the "printing" of alternating layers of food slices on the substrate. The apparatus has particular utility in the production of premade food set ups having a plurality of alternating layers.

  • Patent number: 5391387
    Abstract: Partially formed products (2) are placed in molds (8) and a fluid such as air or an edible filler is injected into the partially formed products (2), e.g. by needles 17[see FIG. 6], so as to cause expansion and thereby produce final products (2) having the shape of the molds (8). Each mold (8) may comprise an upper mold part (14) and a lower mold part (11). The lower mold parts (11) may be mounted on a chain conveyor (9, 9b, 9c) [see FIG. 1] or a rotating cylinder (28) [see FIG. 12] so that the partially formed products (2) are moved towards and the final products (2) are moved away from a reciprocating assembly (12, 13) which carries the upper mold parts (14). Preferably, the final products (2) are retained in the upper mold parts (14) and then ejected by a blast of air. The invention enables complicated shapes to be formed at high production rates while using an economical amount of chocolate or the like.

  • Patent number: 5385745
    Abstract: A method and apparatus for mixing and forming dough into plural discrete product units on a carrier and storing the ready to bake product, and a vending method and apparatus for separating the product from the carrier, baking the product and delivering the product, such as cookies or the like, to a customer. The mixed dough is formed into units, typically disk-like, and placed in a pattern on one or more first carrier sheets, then second carriers are applied with the product laminated between the sheets. The sheets and product can be fan-folded into containers, such as conventional boxes, which can be stored until needed. The containers are placed in a vending machine which leads the sheet assemblies to a station where the carrier sheets are removed and the product is dropped onto a surface that is moved through a convection oven for baking, then through a cooling station. The selected number of product units is dropped into a serving tray and presented to the customer.

  • Patent number: 5384142
    Abstract: Apparatus and processes for the production of food products based on an extruded dough are based on a novel extrusion die for extruding, preferably on a continuous basis, a multi-layer, laminated dough mass from a single die opening. A chamber within the die contains a divider bar for dividing the flowing dough mass into a plurality of dough masses that are united prior to extrusion through the die opening. When the dough mass is cooked, it partially delaminates to provide a desired texture. The desired texture, which can range from relatively dense to relatively light and flaky, is obtained through adjusting the position of the divider bar within the extrusion die and/or the geometry of the divider bar.

  • Patent number: 5374436
    Abstract: A system and method for making a frozen confection having a plurality of differently flavored or colored sections are provided. After partially freezing in a mold the ingredients for a first flavor or color to form a frozen outer layer and a liquid inner core, the liquid inner core is vacuumed from the mold. A carving tool, such as a laser, then is inserted into the area of the mold previously occupied by the liquid inner core. The carving tool removes a portion of the frozen outer layer in accordance with a predetermined pattern. The ingredients for a second flavor or color then are inserted into the mold to fill the inner core and the areas of the outer layer removed with the carving tool. The mold then is subjected to freezing to form the final product.
