SE460573B - PROCEDURES FOR THE PREPARATION OF GRANULATED DRIED SKIMMILK FOR USE AS HIGHLY FEEDING AGENT - Google Patents

Description

The object of the invention is to reduce the total input for the production in the production of the skimmed milk dry product and, through its nature in utilization, to achieve a higher energy delivery and thus a better utilization of the product. The object of the invention is thus to provide a dried skimmed milk. son is distinguished by a long shelf life and thus good storage capacity as well as by metabolic processes through good physiological compatibility unde: a delayed energy loss and easy dosability.

According to the invention, the task is thereby solved. that skimmed milk down to a solids content of 25-15 wt. At a product temperature of 32B ° K to 338 ° K and a residence time of at least 0.5 h, the product is granulated with a compact density of at least_p> l.lS g / cha. Continuously or quasi-continuously is added to an average dianeter of the sprouts or <0.45xdgtanu1at grind. granulated. artegen product with a moisture content of max ll t in an amount of <40 t of the extracted granulate. Thereafter, the cooling of it is classified as 5 mn. extracted the granulate to <3oa ° x.

The granulate production process is designed continuously. by preparing a second storage container for the skim milk already during the actual granulation process. to be treated. in order to prevent a mixture of skimmed milk still present in the container and freshly added skimmed milk from being excluded, and that no insidious spoilage can thereby occur either. In doing so, it must be ensured. that a continuous flow of the heated skimmed milk is maintained during the connection from one container to the other container. The skimmed milk thus prepared functions as granulated. dried skimmed milk product in a way that fulfills the task assigned only in those cases. then at the predicted product temperature .. -ß - mi. wreck; 10 15 20 25 "" 460 cool ninini residence time is maintained and the compact density is reached. Due to the suitably achieved compact density, a slow dissolution of the product is achieved during the night melting and thereby a good compatibility and usefulness.

Embodiment Example A In a container down a 200 l drawer, a water content of about 50% by weight is fed into the barrel of a tin. Skunjölken is protected to 3l3 ° K. With the help of a dosing puncture, the material is fed via a pipeline continuously down about 105 kg / h to a two-component nozzle. which is arranged in a fluidized bed apparatus. The temperature and the ignition concentration then remain constant. In the fluidized bed apparatus (the skin layer is inserted down 294 kpa (3 at) on the solid surface of the fluidizing granulate. Through which it grows. that of the granulation drying process, the vortex layer is fed quasi-continuously with about 15 kg / h of specific granules down an average dianeter of 2 nn and a moisture content of 0.1 wt. t. The granules are fed via a classifying outlet, the granules are fed via a rotating lock into a vortex head cooler, when the granules are cooled by suction of exhaust gas of 303 DEG C. The finished granulation product strand is lowered to about 73 kg / h in two product bins. 50 kg / h is transported to storage as a final product with a water content of 9.1% by weight and a diameter of S the ktströnnen of 15 kg / h in a linkable crushing plant is crushed to an average diameter of 2 nn and returned to the vortex layer for the maintenance of the granulation process. The process can be depleted continuously. due to the fact that a second container was prepared already during the granulation drying process. This can be ensured. that no decomposition processes take place before the granulation drying. än ". .. -v fl wziiwe-.w mu-» u-'uen
