摘要:
A method is disclosed for forming haploid tomato plants. Plants so formed are normal, flowering plants but are sterile. Methods are taught of doubling the chromosome number of the haploid plants to form fetile, true breeding diploid tomato plants. Such methods are useful in plant breeding programs to produce new assortments of genes in true-breeding lines without the several backcrossing steps otherwise required.

A method is provided of producing variant plant varieties of Lycopersicon spp. by tissue culture techniques employing 6-benzyladenine at high concentrations. The technique produces phenotypic variants that are the result of heritable nuclear genetic changes.
摘要:
Apparatus and method for continuously heating and cooling particulate food material are disclosed wherein a pressurized steam treatment chamber is directly coupled to a pressurized cooler in which hot particulate food material discharged from the treatment chamber is cooled by direct contact with a coolant fluid.

This invention provides a rotating drum screening apparatus for continuously and controllably separating a tomato macerate into a reduced insoluble solids pulp fraction and an insoluble solids-enhanced pulp fraction, the rotating drum screening apparatus has an adjustable means mounted on the rotary drum in the path of the influent, insoluble solids-containing liquid which blocks a desired portion of the drum surface so that the effective filter area of the drum surface can be altered as desired.
摘要:
A process for preparing acidified meat chunks suitable for inclusion into a high acid liquid food product is described. A meat paste is extruded into discrete agglomerates which are dropped into a suitable coagulating bath. The agglomerates then are cooked and acidified by submersion in a hot acid bath.
摘要:
Apparatus and method for continuously cooking and sterilizing particulate food material are disclosed wherein the outlet of a pressurized steam treatment chamber is sealed by hydrostatic sealing means in which sterilized, particulate food material is simultaneously cooled and depressurized as it is removed from the treatment chamber.
摘要:
Apparatus for dispensing uncompacted rice upon each of a continuously-moving train of plates from a hopper containing an auger which is rotated to effect dispensing only when a plate is in position beneath the outlet of the hopper. The hopper is caused to swing back and forth about an axis at right angles to the direction of motion of the plates, so that the outlet of the hopper swings downstream at about the same speed as the underlying plate while the auger is operating, thereby to concentrate the dispensed rice on a predetermined part of the plate. The timing may be such that, while the hopper is executing its upstream return motion, the next plate passes beneath it without receiving rice, the hopper dispensing only upon every other plate; another similar hopper at a downstream position then provides similar rice deposits upon similar parts of those alternate plates which do not receive rice from the upstream hopper. A wiper arm preferably wipes the hopper outlet clean of rice at the end of each dispensing operation.
摘要:
A system which dispenses sauce or the like onto selected areas of plates moving in a train beneath a dispenser. The areas upon which the sauce is to be dispensed may for example be those containing meat portions of non-uniform width in directions normal to the direction of motion of the plate or the conveyor. A slot-shaped dispensing aperture on the lower side of the dispenser is automatically opened and closed progressively by a movable closure in such manner that the length of the open portion of the slot matches the corresponding dimension of the areas to be dispensed upon as they move beneath the dispenser. This enables complete coverage of these areas with the sauce, without dispensing it upon other portions of other areas where it is not desired.
