摘要:
On a mis au point un procédé permettant le séchage et/ou la congélation de matière granulaire et analogue sous forme de particules, notamment de matières organiques. On soumet la matière granulaire à un agent de séchage ou à un réfrigérant arrivant d'en dessous, se trouvant dans un jet sensiblement vertical aidant à maintenir la matière granulaire en mouvement. Dans une boucle de circulation (10) se trouve une chambre de séchage (11), comportant un organe (13) permettant de laisser passer l'agent de séchage et/ou le réfrigérant. Dans ladite boucle se trouve une unité de pompe à chaleur (12) comprenant un condenseur principal (19), afin de chauffer l'agent de séchage, ainsi qu'un condenseur auxiliaire (21) éliminant la chaleur excédentaire. On a également prévu une vanne de répartition (23) répartissant le réfrigérant à partir d'un évaporateur (15) jusqu'aux deux condenseurs, selon les besoins d'alimentation en chaleur de l'agent de séchage et/ou du réfrigérant.
摘要:
A method for preparing dehydrated fruits, vegetables and tubers, particularly potato products. The steps of the method including boiling whole, slices or pieces of the raw edible product for a time sufficient to partially cook the starch and soften the tissue of the edible product; comminuting the cooked product; and drying the comminuted product. The raw edible product is preferably unpeeled or partially peeled. The resulting dehydrated product (500) retains more Vitamin C has a lighter color, a high percent of free amylose, less broken cells and less degradation products than a corresponding product produced by conventional methods.

The present invention relates to a method and device for drying mash-products, and more particularly to a 2-step device for drying mash-products comprising a first drying unit (a flow rotary drying unit) and a second drying unit (a mixing rotary drying unit), the first drying unit and the second drying unit being arranged in series, and a 2-step method for drying mash-products.
摘要:
The present invention relates to a process for preparing a dehydrated food composition, said process comprising the preparation of a vegetable-based puree and dehydration of said by puree by drum drying. The dehydrated food composition so obtained can be stored for a long period prior to reconstitution with water and imparts a very balanced, authentic vegetable flavour upon such reconstitution. There is a need for drum dried ingredients providing improved flavour and fragrance retention. It is surprisingly found that flavour and fragrance retention of drum dried vegetable-based compositions is improved substantially when including a starch having a high amylopectin to amylose ratio and a relatively small particle size.

Une matière alimentaire pâteuse est répartie à une partie supérieure d'un cylindre sécheur 1,2 mobile en rotation, le mélange adhérant à la surface externe dudit cylindre. Le film est décollé du cylindre sécheur, après plusieurs tours de celui-ci, par un dispositif constitué d'un racleur 6 commandé par une capteur 10 mesurant la rotation du cylindre sécheur. Application à la production de flocons de céréales épais.

摘要:
A method for drying and/or freezing granular and similar matter in a particle form, particularly organic materials. The granular material is subjected to a drying agent or refrigerant from below in a mainly vertical jet which helps to keep the granular material in motion. There is a drying chamber (11) in a circulation loop (10) with an organ (13) for the through flow of the drying agent and/or refrigerant. In the loop there is a heat pump unit (12) comprising a main condenser (19) for heating the drying agent and an auxiliary condenser (21) for the removal of the surplus heat, there is also a distribution valve (23) to distribute the refrigerant from an evaporator (15) to the two condensers, in accordance with the need to supply heat to the drying agent and/or refrigerant.
