Abstract: <PICT:0621207/III/1> <PICT:0621207/III/2> The glue water obtained on the cooking of marine animal tissue such as whale meat or herrings is expressed from the cooked material and concentrated by evaporation at super-atmospheric pressure in order to obtain steam under pressure for the cooking of further raw material.  With the apparatus of Fig. 1, steam at 148 DEG  C. from a boiler 1 is passed to a pressure evaporator 2 for the glue water, the condensed water being returned to the boiler through a pipe 3, and the steam, at 133 DEG  C., from the glue water being concentrated in the evaporator 2, is passed through a pipe 5 to a raw material cooker 6, the glue water here produced being passed through a pipe 9 to the pressure evaporator 2 and the concentrated glue water being withdrawn from the evaporator by a pipe 7.  In the apparatus of Fig. 2, there are three successive pressure evaporators, steam evolved from the glue water in the evaporator 2 being passed to heater tubes in an evaporator 2a and the glue water being passed from evaporator 2 into evaporator 2a for further concentration, steam evolved from the glue water in the evaporator 2a being passed to heater tubes in an evaporator 2b and the glue water from evaporator 2a being passed to evaporator 2b for final concentration, and the steam liberated from the glue water in the evaporator 2b being passed to the raw material cooker 6.  The Specification as open to inspection under Sect. 91 comprises also the employment of any evaporator for obtaining vapour from the glue water for heating further raw material.  This subject-matter does not appear in the Specification as accepted.ALSO:An ingredient of animal food is obtained by cooking marine animal tissue such as whale meat or herrings, expressing the glue water from the cooked material and evaporating the glue water at super-atmospheric pressure in order to obtain steam pressure for the cooking of further raw material, the evaporation being carried out in two or more stages if desired, and the concentrated glue water being subsequently evaporated to dryness if desired.  The concentrated glue water or the dried product may be mixed with the material from which the glue water was separated after the latter has been pressed for oil.  The Specification, as open to inspection under Sect. 91, comprises also the employment of any evaporator for obtaining vapour from the glue water for heating further raw material.  This subject-matter does not appear in the Specification as accepted.ALSO:A glue is obtained by cooking marine animal tissue such as whale meat or herrings, expressing the glue water from the cooked material and evaporating the glue water at superatmospheric pressure in order to obtain steam under pressure for the cooking of further raw material, the evaporation being carried out in two or more stages if desired, and the concentrated glue water being subsequently evaporated to dryness if desired.  The Specification as open to inspection under Sect. 91 comprises also the employment of any evaporator for obtaining vapour from the glue water for heating further raw material.  This subject-matter does not appear in the Specification as accepted.ALSO:A food ingredient is obtained by cooking marine animal tissue such as whale meat or herrings, expressing the glue water from the cooked material and evaporating the glue water at superatmospheric pressure in order to obtain steam under pressure for the cooking of further raw material, the evaporation being carried out in two or more stages if desired, and the concentrated glue water being subsequently evaporated to dryness if desired.
