Patent number: 5132133Abstract: A crisp, palatable, reduced calorie whole grain snack food is produced by subjecting initially tempering whole grains such as wheat, barley, corn, oats, rice and sorghum to a micronizing process wherein the whole grain(s) are partially precooked through application of near infrared radiation. Thereafter, the micronized grain is mixed with water and other optional ingredients and preconditioned with agitation and steam/water addition. After preconditioning, the mixture is directed to a twin screw extruder in order to form an extrudate of desired shape and size. The extrudate is then heat treated to crisp the outer surface thereof, typically through the use of oven heating and/or frying. The resultant snack product preferably has a whole grain content of at least about 50% by weight and a low total fat content on the order of about 20% by weight or less.Type: GrantFiled: September 11, 1991Date of Patent: July 21, 1992Assignee: Wenger Manufacturing, Inc.Inventors: Gordon R. Huber, Marc L. Wenger, Eric S. Sevatson

Patent number: 5114488Abstract: An improved, low cost, energy efficient extrusion device and method for processing of cellulose, hemicellulose, and like fiber-bearing materials is described which includes a pretreatment extrusion zone and a reaction extrusion zone separated by a pressure sensitive variable die. The method hereof includes the steps of extruding cellulosic material through the pretreatment zone at an elevated pressure and temperature, passing the material into the reaction zone where it is mixed with an acid and is processed at a lower pressure and temperature than in the pretreatment zone, and extruding the material through a final extrusion die. The surging and blowing usually experienced with extrusion of fibrous material is drastically reduced by the unique construction of the extruder die members. The cellulosic material may be hydrolyzed to simple sugars in accordance with the method and apparatus hereof with a minimum of acid degradation of the extrusion equipment.Type: GrantFiled: December 5, 1988Date of Patent: May 19, 1992Assignee: Wenger Manufacturing, Inc.Inventors: Gordon R. Huber, LaVon G. Wenger, Bobble W. Hauck, Galen J. Rokey, Lawrence E. Schmelzle, Timothy R. Hartter

Patent number: 5059439Abstract: Quick cooking pasta products are extruded in a low temperature process by advancing a partially pre-cooked mixture of pasta flour and water prepared in a preconditioner along the length of a screw extruder through a cooking zone, then through a venting zone and a forming zone, and finally through an extrusion die to yield an extruded product. The mixture has a maximum temperature of 215.degree. F. in the cooking zone in order to substantially eliminate the formation of darkened specks in the final extruded product which would otherwise represent portions of the mixture that are burned during cooking. Limiting the mixaimum temperature of the mixture in the extruder also greatly enhances the extruded pasta quality by increasing product resistance to overcooking and improving the retention characteristics of the original product integrity.Type: GrantFiled: November 12, 1986Date of Patent: October 22, 1991Assignee: Wenger Manufacturing, Inc.Inventors: Marc L. Wenger, Gordon R. Huber

Patent number: 4981711Abstract: A texturized sinking shrimp and fish food is produced in the form of an extrusion cooked, cellular produce which is self-sustaining in ambient temperature water for a period of at least four hours and is made up of a mixture of at least 8 percent marine meal with up to 60% vegetable protein flour. The product is prepared by mixing and then partially cooking the starting materials in a preconditioner and then introducing the precooked mixture into an extruder (preferably of the twin screw variety) for texturization. During extrusion, the protein within the mixture is developed into laminar striations, which ultimately yields a layered, open-celled, high protein product having a specific gravity greater than 1.00 which will not readily decompose in water during consumption by the shrimp and fish.Type: GrantFiled: June 2, 1989Date of Patent: January 1, 1991Assignee: Wenger Manufacturing, Inc.Inventors: Joseph P. Kearns, Gordon R. Huber

Patent number: 4963033Abstract: An extruder for processing wood particles, shavings or sawdust is particularly useful for the production of a refined product exhibiting a large number of separated, individual fibers each of a relatively long length as is desirable in the production of a fiber core for a composite particle board. The extrusion apparatus comprises an elongated barrel and a flighted screw rotatable within the barrel, with the final downstream section of the screw being of a configuration to sequentially present three processing zones each having a compression region, a restricted region and a decompression region. The three processing zones of the final screw section cooperate with a compression region and restricted region formed in the final head section to choke the advancement of wood materials through the extruder sufficiently to enable satisfactory processing of the same without the use of a final die or restricted orifice disposed on the outlet of the extruder barrel.Type: GrantFiled: October 19, 1988Date of Patent: October 16, 1990Assignee: Wenger Manufacturing, Inc.Inventors: Gordon R. Huber, Lawrence E. Schmelzle

Patent number: 4769251Abstract: Quick cooking rice products are manufactured in a low mechanical shear extrusion process by first pre-cooking a rice and water mixture in a preconditioner and then advancing the mixture along the length of an extruder sequentially presenting a cooking zone, a venting zone, a forming zone, and finally an extrusion die to yield an extruded product. Venting of gaseous products removes a significant amount of moisture from the mixture during the time that the latter passes between the cooking zone and the forming zone, and consequently the moisture content of the mixture within the cooking zone can be increased in order to reduce the total mechanical shear imposed on the mixture during the cooking process. The extruded product, once dried, closely resembles rice grain and readily rehydrates without exhibiting slimy or sticky characteristics, and has an increased tolerance to overcooking.Type: GrantFiled: February 3, 1987Date of Patent: September 6, 1988Assignee: Wenger Manufacturing, Inc.Inventors: Marc L. Wenger, Gordon R. Huber
