Abstract: A roasting system and method for avoiding contact between food to be roasted and combustion materials, in which a heat exchanger is heated by a heated flow from a combustion chamber and the heated flow exhausts through an exhaust outlet associated with the heat exchanger. To avoid food contact with the heated flow, an intake air flow duct draws in outside air and conveys the drawn-in air past the heat exchanger free of contact with the heated flow or heated material forming the heated flow for heating the drawn-in outside air by induction. A surround chamber surrounding the combustion chamber in heat exchange relationship therewith is connected with the intake air flow after it is heated by the heat exchanger for conveying the heated intake air flow to the surround chamber for heating thereof the surround chamber by heat from the combustion chamber, then the heated air flow is conveyed to a roasting chamber for heating the food.

Abstract: A custard product is prepared by passing a container containing a liquid custard mix through a microwave field and exposing the liquid mix to microwave field energy, but so that microwave field energy at a position below a position of a base of the mix in the container is reflected away from the mix base, for a time to heat the custard mix to initiate setting the mix and so that upon leaving the field, a contained custard product has a temperature of from 90.degree. C. to 95.degree. C. The custard product then may be exposed to infrared energy to firm and brown the product.

Abstract: The invention relates to a process for optimizing and balancing the composition of the ration feed given to a ruminant by taking a single sample or urine or milk from the ruminant and evaluating the nutrient status of the fore-stomachs with reference to energy and protein. The process comprises: measuring the excretion of urea in the sample; measuring the excretion allantoin in the sample in relation to the excretion of creatinine to calculate an allantoin:creatinine ratio; evaluating the nutrient status of the fore-stomachs as to protein and energy; and adjusting the protein and/or energy content of the ration feed to an optimum level. The calculation of the allantoin:creatinine ratio allows for a single sample of urine or milk to be used in the evaluation of the nutrient status of the ruminant's fore-stomachs.

Abstract: A method for manufacturing intermediate products for preparation of animal feeds comprising the steps of: (a) heating a crude granular raw material in a vessel containing a heating device at a temperature sufficient to toast the raw material; (b) feeding the toasted crude raw material from the vessel to a container; (c) cooling the toasted raw material within the container by contacting the toasted raw material with cold air in counterflow to the feeding of the toasted raw material in order to heat and moisten the cold air and to cool and dry the raw material so as to obtain the intermediate products; and (d) feeding the heated moist air back to the vessel thereby recovering the energy from the heating step (a).

Abstract: A method is disclosed for accelerating the ageing process and sterilizing raw meat for extended storage at refrigerated temperatures by treating the meat at ultra-high temperature (UHT), e.g. 900.degree. to 1200.degree. C., for a time sufficient to denature proteins, without burning, to a depth of up to about 2 mm. After UHT treatment the meat is cooled to a refrigerated temperature and packaged in a hermetically sealed container. The meat can be rendered storage stable at ambient temperatures by subjecting the hermetically sealed meat to electron beam radiation (EBR) at an irradiating dosage sufficient to destroy all mesophilic vegetative pathogens, spores of pathogens, toxins, and spoilage microorganisms which grow at ambient temperatures.

Abstract: The inventive method and apparatus suggests guiding the pasta directly into a drying climate after exiting from the die. Pasta strands of short goods are fed directly into the drying device from the extrusion die. The pasta strands can be cut either directly at the extrusion die or subsequently into packaging lengths after drying by means of an additional cutting device. It is possible to operate only the initial drying in this way, particularly to heat up the goods and then to carry out the final drying in a manner known per se, e.g. by portions. However, it is also possible to carry out the drying in its entirety, i.e. the pre-drying and final drying, according to the invention, particularly for short goods. The goods can be intensively dried at previously unaccustomed temperatures of 90.degree. C. to 120.degree. C., particularly during final drying from 15% to less than 13% product moisture.

Abstract: Input food is extruded or otherwise deposited between a pair of counter-rotating wheels whose outer surfaces define mold cavities. The deposited input food is molded into pieces having desired shape (e.g., simulating pitted prunes or berries) by compression between aligned, counter-rotating mold cavity pairs. Preferably, the input food is heated prior to molding to prevent irreversible set up before compression between the mold cavities, and the wheels are chilled to cause deposited food to set up as it is compressed and carried between aligned, chilled mold cavities from a loading station to a release station. Preferably, the mold cavities are maintained at low temperature (e.g., in the range from about -10.degree. F. to 32.degree. F.). After the input food is molded and set up into pieces, the rotating cavities separate at a release station, allowing the molded pieces to fall away from the wheels.

Abstract: A stream of dough passes from a metering pump (16) or (17) into the dough distribution manifold. The incoming stream of dough is sliced by the sharpened knife edge (64) of the divider knives (51) to form a pair of diverging streams of dough. Each diverging stream of dough is confronted with a second pair of divider knives (52) and (53), where a similar dividing function occurs. The positions of the knives are adjustable by external knobs (75) so as to balance the diverging streams of dough. The dough streams pass directly, in a line of sight, from the inlet openings (43) to the outlets (44A-44H), thereby avoiding the movement of dough about bends, turns, protrusions and obstructions which would deteriorate the gluten structure of the dough.
