Abstract:
The invention relates to a device (10) for puffing grains (19), especially cereals and pulse, comprising a heating device (12) for preheating the grains (19) and a puffing reactor (14) for puffing the grains (29). In order to ensure brief, effective and even heating of the grains, the heating device (12) has a free jet fluidized bed (16) with no inflow bottom, in which a batch of grains (19) to be heated is exposed to a heat-conducting gaseous medium (25) during a batchwise preheating process in synchronization with the puffing process.
Abstract:
The present invention generally relates to the production of direct expanded farinaceous food products without the use of a drying apparatus such as an oven and without the use of traditionally used sugar to eliminate such drying steps. A farinaceous material combined with a plasticizer component in the form of trehalose is extruded to form a direct expanded shelf-stable snack food product. Snack food products made with trehalose can be incorporated into an outer shell of a composite center-filled or co-extruded product.
Abstract:
A composition comprising from about 3 % d.s.b. to about 35 % d.s.b. of a first starch, wherein the degree of substitution (DS) of the first starch with a hydroxypropyl group is from about 0.1 to about 0.6; from about 10 % d.s.b. to about 50 % d.s.b. of a second starch; and from about 15 % d.s.b. to about 87 % d.s.b. of a flour or a meal. A method, comprising extruding a composition as described above and from about 15 % total weight to about 25 % total weight water at a temperature from room temperature to about 200°C, to yield an extruded composition comprising less than about 5 % total weight water.
Abstract:
One or more of hydrolysed wheat flour, soluble dietary fibre, prebiotic dietary fibre, polydextrose and soluble corn fibre ate used as basic matrix-forming ingredients in an expanded food product. The matrix-forming ingredients are mixed together with water, plus a whey protein isolate or whey protein concentrate,to increase the protein content of the food. A dough is formed which is then formed into pieces which are temperature conditioned before being expanded under a vacuum caused by evaporation of moisture in the dough. All steps of the process of making the expanded food products, including any subsequent drying, is carried out at a temperature not exceeding 75 °C, which advantageously allows mixing in of temperature sensitive ingredients, e.g. vitamins, pharmaceuticals, at the dough forming stage. The products have a honeycomb structure and there is no significant change in flavour or nutritional value of the ingredients caused by the process of manufacture. Advantageously, acrylamide formation is also avoided.
Abstract:
Die Erfindung betrifft Verfahren zur Herstellung von Aquafeed, insbesondere von Futterpellets, wobei die Rohstoffe ggf. nach vorheriger Mischung extrudiert werden und anschliessend zu Pellets verarbeitet werden, dadurch gekennzeichnet, dass extrudiertes Produkt zunächst in einer Expansionskammer gezielt expandiert und erst nach Passieren einer weiteren Formungseinrichtung in Pellets geformt wird.

Abstract:
El objeto de esta invención es el de un reactor para procesamiento de alimentos de forma geométrica compuesta, además de una tapa atornillada en la parte superior, cuyo principio de operación para generar altos niveles de temperatura y presión será el de ultilizar aire caliente, proveniente de un compresor en serie con un intercambiador de calor, y que suministrado a través de 3 entradas diseñadas en posición y ángulo para que, en combinación con el diseño helicoidal del interior y una salida de alivio genere un efecto torbellino que mantenga el alimento en constante movimiento durante todo el tiempo de ciclo del proceso. El reactor está equipado con válvulas de entrada y salida de acción rápida tipo mariposa accionadas por actuadores mecánicos, así como sensores de presión y temperatura, todos conectados en red y manejados por un Controlador Lógico Programable que moni torea los parámetros y ejecuta las acciones por medio de software.
Abstract:
An expanding and extruding apparatus comprises an extruding cavity (3). An extruding screw (1) associated with the extruding cavity is provided in the extruding cavity. A stabilizing and extruding member (4) connected to the extruding cavity is provided at the output of the extruding screw, an extruding hole (8) being coaxial with the extruding screw is provided on the stabilizing and extruding member. An extruding nozzle (19) is provided at one side of the stabilizing and extruding member and a cutter (20) driven by a motor abuts against the outside of the extruding nozzle. A heat exchanger and a converging member (17) connected each other axially are provided between the stabilizing and extruding member and the extruding nozzle. A converging hole (18) communicating with the extruding nozzle is provided in the converging member. The heat exchanger comprises some exchanging pipes which are throughout its case (10) parallelly and the exchanger and the case are connected tightly. The case is equipped with a cooling-medium inlet (14) and a cooling-medium outlet (12). Every exchanging pipe communicates the extruding hole and the converging hole respectively. The expanding and extruding apparatus can improve the maturing quality and control the expansion degree of products so as to stabilize their feature in the food and forage industry.
