摘要:
The invention relates to a film tube (10) based on cellulose which is produced by extruding an aqueous cellulose-N-methyl-morpholine-N-oxide (NMMO) solution through a ring nozzle (21) onto a lining (3). The film tube (10) is manufactured by means of a vertically descending spinning in a spinning vat (12) in which a spinning bath (11) is located. The film tube (10) which is submerged in the spinning bath (11) passes through an air gap (9) between the underside of a nozzle block (7) and the upper surface of the spinning bath (11) and, internally, is pressurized, supported and slightly stretched in a transversal manner by compressed air. The film tube (10) is filled with an inner bath solution (31) via a supply tube (18). An idle roller (13) is situated near the bottom of the spinning vat (12) in order to guide the film tube (10) around and, afterwards, out of the spinning vat (12) in an upward sloping manner. The film tube is laid flat along a contact section (27) of the idle roller (13).
摘要:
For production of a seamless edible cellulose tubing from underivatized cellulose, a solution of the underivatized cellulose in tertiary amine N-oxide, of additives and water, is extruded as tubing from an annular die and conducted through an air gap into a water bath. The cellulose tubing is conducted out of the water bath, cleaned by spraying with heated water and thereafter passed through at least two wash sections and a plasticizing section. After exit from the plasticizing section, the wet cellulose tubing is predried in the laid-flat state, before it is dried to its final moisture. The predryer 13 is arranged vertically or horizontally and consists of an insulated tube to which is fed air heated by a heat exchanger in an accurately metered amount and at a constant temperature of up to 130° C. The main dryer 19 is arranged horizontally and contains tangentially and radially directed air nozzles, the air jets of which keep the inflated cellulose tubing 20 suspended during the drying operation.

The invention relates to tubular, edible food casings which include cellulose, at least one protein and at least one filler in which the ratio of the wet tear strength in the transverse direction to the wet tear strength in the longitudinal direction is from 1.3:1 to 1:3.5. The casing is gathered to form a shirred stick which is particularly suitable for processing on high-speed stuffing machines. The sticks can be deshirred and stuffed with sausage meat emulsion without difficulty on the stuffing horn. The sticks are particularly suitable in the production of cooked-meat sausages and scalded-emulsion sausages and frying sausages, especially small sausages in which the casing is co-consumed.

The present invention provides a seamless tubular film on a cellulose base, being produced by extruding an aqueous cellulose N-methyl-morpholine-N-oxide spinning solution. The maximum degree of roughness Rmax is from greater than 0.1 &mgr;m to 0.5 &mgr;m and an average degree of roughness Rm is from 0.005 to 0.014 &mgr;m. On the surface of the tubular film is formed in contact with an electrolyte an electrokinetic potential, the size of which depends on the pH value of the electrolyte.
摘要:
A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition comprising a cellulose hydrate and a plasticity enhancing amount of at least one substantially water insoluble plasticizing ester of an aliphatic monocarboxylic acid containing from about 9 to about 24 carbon atoms and a polyalcohol comprising at least two hydroxy groups at least one of which is esterified with said aliphatic monocarboxylic acid, and water and/or a plasticizer.Such shaped articles can be prepared by mixing a viscose solution with a liquid containing the plasticizing ester, introducing the resulting mixture into a precipitating bath and drying the precipitated shaped body. Tube-shaped articles are especially suited as sausage casings.

A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition of high mechanical strength which is obtained by reacting a plasticized cellulose composition obtained by treating cellulose hydrate with a plasticity-enhancing amount of at least one plasticizing alkyl derivative which comprises an alkyl containing from about 8 to about 24 carbon atoms and which is selected from the group consisting of alkylamido-bis-dimethylene-triazinone-tetramethylol, alkylamino-bis-dimethylene-triazinone-tetramethylol, a substantially water insoluble ester of an aliphatic monocarboxylic acid containing from about 9 to about 25 carbon atoms, and a polyalcohol, such as glycerol or polyethylene glycol with a cyclic dimethylolurea derivative, and water and/or a plasticizer.Such shaped articles can be prepared by mixing a viscose solution with a liquid containing the plasticizing alkyl derivative, introducing the resulting mixture into a precipitating bath, washing the precipitated shaped body in the gel state, treating it with an acidic solution of the cyclic urea compound and drying it in the heat. Tube-shaped articles are especially suited as sausage casings.
摘要:
The invention relates to a food casing from a two-dimensional fiber structure, which is coated on one or both sides with acrylic resin. The acrylic resin is combined with at least one other natural and/or synthetic polymer. The acrylic resin in the coating may be admixed with the other polymer. The latter can also form a layer of it's own. On the inside of the casing (i.e. on the side facing the food), this coating prevents gelling out, while at the outside it has a mainly permeability-increasing effect. The casing is particularly used as artificial sausage casing, especially for cooked-smoked sausages.
摘要:
The invention relates to a double-viscosed fibrous cellulose sausage casing having a pigmented outer cellulose hydrate layer and an impregnated internal cellulose hydrate layer. The impregnation of the internal cellulose hydrate layer includes a collagen hydrolysate and the outer cellulose hydrate layer includes at least one white pigment, preferably having titanium dioxide pigments. The invention further relates to a method for producing the fibrous cellulose sausage casing and also to its use as artificial sausage casing.
