The drying process for products on an atmospheric double drum dryer includes three phases: Phase 1: The formulation and processing of the ingredients to be dried with water in a slurry form and metered to a double drum dryer for drying
Get PriceA double drum dryer working under atmospheric pressure was developed for water evaporation rate of 20 kg/h. Potato slurry of 12% solid concentration was dried to obtain potato flakes. Experiments were carried out at drum speed of 5 to 30 rpm, steam pressure 2 to7 kg/cm(2) gauge (saturation temperature 120-164 C) and liquid level 5 to 10 cm at the nip of drums
Get PriceAtmospheric Double Drum Dryer. This is basically a conduction dryer. Wet feed (in liquid or paste form) is fed in nip between the two drums and is applied on the outer surface of both the rotating metal cylinders. Steam at required pressure is admitted into the individual drums via rotary joints for heating
Get Price1.2 Equipment. Depending on the design, the product is applied continuously as a thin film at the bottom or on top of the main drum. As the drum rotates and is heated on the inside, the product dries on the outside of the drum surface. The short exposure to a high

Get PriceDrum dryers are classified into single drum dryer [Fig. 1(a)], double drum dryer [Fig. 1(b)], and twin drum dryer.[3] A double drum dryer has two drums that revolve toward each other at the top. The spacing between the two drums controls the thickness of the feed layer applied to the drum surfaces. A twin drum dryer also has two
Get PriceThe double drum dryer A double drum dryer is often used for prod-ucts with lower viscosities. The product is fed into the sump between the two drums. The distance between the drums can be adjusted accurately to control the layer thickness on the drums. In addition, appli
Get PriceDouble-drum stainless steel roll dryers are a staple in many material manufacturing processes. Drum drying is ideally suited for high or low solids content, high molecular weight water-soluble polymers. A delicate balance between feed rate, roll speed, steam pressure and roll gap is maintained to ensure a consistent product that meets the
Get Price60x120 VDDD. 314.2 sq ft. Vacuum Double Drum Dryers are specified when products require uniform low-temperature drying, non-reactive atmosphere drying or complete solvent isolation and recovery drying. Utilizing thin film drying via conductive heat transfer under vacuum, these dryers can be designed to meet the most stringent sterile operating
Get PriceDec 06, 2018 Rotary Dryer Machine Working Principle: Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that

Get PriceDOUBLE-DRUM DRYER WITH APPLICATOR ROLLS The double-drum dryer with applicator rolls is your best choice if you have a more variable product range because it combines the advantages of both the single-drum and double-drum dryer systems. The main drums can be moved apart hydraulically and, as such, can be used as two single-drum dryers with
Get Pricemechanism prior to design work is strongly recommended. In drying of wet solids, the following main factors, which essentially are used in process design calculation of dryers should be defined in accordance with mass and heat transfer principles, process conditions and drying behavior: - Drying characteristics. - Constant-rate period
