The membrane was then dried on a drum drier at 95° C.

The preparation mixtures may also be passed through a drum dryer.

Subsequently, the membrane samples are fully dried at 110° C. in a drum dryer.

The solution treated in this way was dried on a drum dryer.

Then the membrane is removed and dried on a drum drier at 90° C.

The moist pastes obtained may be dried by means of spray dryers, drying cabinets, cylinder dryers and belt dryers.

The almost homogeneous paste so obtained may subsequently be dried, for example in a roller dryer.

Then the web was dried in a traditional manner on a drum drier at 80° C.

The mixture was slowly heated to the boiling temperature, treated with 7 liters of water and held for 2 hours at the boiling temperature, then adjusted to a pH of 4.6 with ammonia, cooled, dried on a roller drier, heated in a tubular rotary drier to 300° C. and ground in a spike mill to a particle size below 0.5 mm.

The membrane thus dried is then immersed in a solution of 0.3% PVP K90, 0.3% copolymer VP/VA 1:1 and 0.5% sodiumperoxodisulphate in water/ethanol 4:1, removed therefrom after 5 seconds, dabbed with paper and dried on a drum drier at a temperature of 90° C.

The gels are then washed and dried. Drying may be carried out in conventional drying apparatus such as drying cupboards, belt driers, roller driers or spray driers.

The resulting coprecipitate was dried at 140° C. on a drum dryer and calcined at 535° C. in a revolving tube and then milled in a pin mill.

The resulting suspension of the coprecipitate was dried on a drum dryer, calcined at 530° C. in a revolving tube and then milled.

Examples of devices suitable for drying are thin film dryers, fluidized bed dryers, spray dryers, band dryers and drum dryers, these dryers preferably being used when the antiblocking agent is added to the mixture before the removal, and the removal takes place by thermal processes.

The neutralized gel is then dried on a drum dryer, pin-milled and finally classified with the fraction 200-850 ?m being collected.

An emulsion containing 1000 g of Trasil (methylsilicone resin, commercial product from Wacker-Chemie GmbH) in 2000 g of a solution of 100 g of a methylhydroxypropylcellulose having an average degree of substitution of about 1.8 and having a flocculation point of from 50° to 55° C. (Methocel A 15 from Dow Chemical) was dried on a roll drier at a roll temperature of 100° C. The product was obtained in the form of small flakes which were readily redispersible in water.

A mixture containing 100 parts by weight of water, 25 parts by weight of an organopolysiloxane composed of 93% by weight of dimethylpolysiloxane (Brookfield viscosity 8000 cps) activated with 7% by weight of silica and methylsilica (S 132 from Wacker-Chemie GmbH) and 2.5 parts by weight of a methyl-hydroxypropylcellulose having an average degree of substitution (DS) of about 1.8 and a flocculation point of from 50° to 55° C. (Methocel A15 from Dow Chemical) was dried on a roll drier at a temperature of 100° C. The product was obtained as a thin, fragile film.

At the end, the hollow fiber, now composed of pure cellulose, passes through a softening bath containing 10 g/l glycerine and 400 g/l isopropyl alcohol in water and then dried on a roller dryer at 75°-80° C. contact temperature to a water content of 10%.

This coil is subsequently treated in an appropriate device in such a manner that the membrane coil is conveyed over an adequately designed saturating bath and a drum dryer, and then rolled up anew.

In industry the polycocondensates can be prepared for example using a heatable drying belt, a paddle dryer, a drum dryer, a tumble dryer or a fluidized bed dryer.

Certain of the disadvantages of the aforementioned apparatus are avoided in a device for automatically loading moistened veneer sheets in a belt or drum dryer and for unloading and stacking the dried veneer sheets, as described in German Offenlegungsschrift No. 2 523 482.

Subsequently, the tow was dried at 135° C. in a drum dryer without allowing any further shrinkage.
