Definitions

  • the invention relates to a method and a plant for drying 5 material which has been divided, comminuted, pelletized, granulated etc.
  • the invention relates to a method for drying divided/pelletized material, especially of animal and/or vegetable origin, in the form of a foodstuff or a feed
  • the invention relates to a drying plant for the implementation of the method and is, moreover, of the kind specified in the is preamble to claim 2.

  • the pellets are added on the uppermost conveyor belt in a warm and moist condition and pass across any intermediate conveyor belts downwards to the lowermost conveyor belt.
  • the direction of transport from the top downwards is reversed from one conveyor belt to the next, so that the uppermost conveyor belt may have the pellets added for example at its left-hand end if the upper section of the conveyor belt has an extent from left to right.
  • At the right- hand end of this upper conveyor belt said pellets leave the belt and fall down on to the right-hand end of the underlying conveyor belt to be moved by this towards the left, and so on.
  • Each conveyor belt may, by identical lengths, be slightly offset in the horizontal direction, so that its receiving end portion extends somewhat beyond the discharge end of the above-lying conveyor belt.
  • the lower conveyor belt receives the air flow as the air temperature and dryness are at their maximums, while the upper conveyor belt receives the air in its coldest and moistest condition, cooled and with condensate added during its passage across the lower and the possible intermediate conveyor belt with drying matter/feed products lying thereon.
  • feed products, articles of food etc. for example in the form of pellets, present on a lower conveyor belt where the warmest and driest drying air is effective, is "over-dried" on the surface, which reduces the product quality.
  • pellets When pellets are supplied to an uppermost conveyor belt, the air coming from below will have become more humid and colder on its way up through the drying layers on the underlying conveyor belt (or in drying boxes in drying cabinets) . As mentioned, the pellets will contain water vapour and additionally have an aqueous film which covers each pellet. When warm pellets, for example at a temperature of about 70 °C, get into contact with even warmer air, which has, for example, a temperature of 120-150 °C, water m the form of water vapour will constantly be extracted from the pellets.
  • Said animal and/or vegetable products require a gentle drying process m order for the physical properties of the feed and the foodstuff not to be harmed or deteriorated during the drying.
  • Foodstuffs for human beings and feed materials for animals and fish are considered sensitive biological material.

  • Such a product needs drying and cooling before it may be used.

  • the drying process normally takes a long time and may last for over an hour.
  • the drying process may be divided into two stages of drying rates :
  • Stage 1 with a constant drying rate, in which there is a great flow of water from within the product (diffusion) causing the product surface to be moist, and
  • Stage 2 with a decreasing drying rate, in which the flow of water from within is reduced and is no longer able continuously to provide the surface of the product with water.
  • the moisture of the product is defined as critical moisture. As mentioned, this is a condition arising when the diffusion forces no longer carry water out to the pellet surface.

  • the drying medium for example air
  • the drying medium may be relatively hot (>100 °C) without heating and damaging the product which is dried because of the energy of the air being used for the evaporation of water, not for heating the product.

  • known drying plants for feed comprises three main components: a drying cabinet of one or more sections; an air heating and circulating system with pertaining channels, fans, cyclones etc.; a control device for the control of said system.
  • drying cabinets for continuous operation consist of either a box dryer or a multilayer belt dryer of one or more drying sections in one and the same cabinet. Drying plants used currently in the feeds industry work as counter-flow dryers, i.e. the warm air mostly encounters the driest product which is leaving the process. The more layers of products passed by the drying air, the more humid the air, As previously mentioned, the uppermost product layer contains the most water. When the drying air reaches this upper, moistest product layer, it contains relatively much water which it has absorbed from the underlying layers of product, and its ability to absorb water from the upper product layer is reduced. This may lead to inefficient drying of the upper product layer, particularly at the dryer entrance. In particularly unfavourable conditions condensation of water from "saturated" drying air may occur in the upper part of the drying cabinet .
  • heater batteries are used, in some of these known drying cabinets, to heat the air and reduce its relative humidity.

  • the drying air is flowing in the direction against the flow of product, so that the drying capacity of the drying air is reduced on the way to the moistest product.
  • the same drying air whose drying properties and capacities are gradually changing, flows all the way through the drying cabinet and gets into contact with product present in different phases of the drying, i.e. with a water content of 20-25 % in an initial phase to 4-8 % in the final drying phase.

  • the invention makes it possible to adjust the temperature and air humidity of each separate air flow to the product consistency in question in the respective drying phase.

Abstract

L'invention concerne un procédé permettant de sécher des aliments granulés en particulier, ainsi qu'une installation de séchage utilisée aux fins dudit procédé. L'air constitue le milieu de séchage, en écoulement forcé, moyennant une température ajustée et une humidité relative. Le procédé vise à assurer à tout moment un séchage optimal du matériau à sécher avec lequel l'installation de séchage est alimentée. Ce résultat est obtenu par le biais d'un processus de séchage à deux ou plus de deux étapes, chaque étape recevant un flux d'air séparé, c'est-à-dire un flux dans lequel les propriétés de séchage (température, taux d'humidité, débit) de l'air sont adaptées à la consistance et à la chaleur (humidité et température) du matériau à sécher pour telle ou telle étape. L'installation comporte au moins deux transporteurs (36, 38) qui, parmi une pluralité de transporteurs de matériau à sécher (36, 38, 40), sont enfermés dans une chambre séparée (30, 32, 34) comportant des entrées et des sorties pour ce matériau et pour l'air de séchage, respectivement, et qui communiquent mutuellement ou avec l'environnement uniquement par le biais de conduites équipées de portes (42, 42', 42'', 42''').
