Embodiment 1

[0042] A vacuum low-temperature drying method for bovine bone glue, comprising the following steps:

[0043] 1) Raw material preparation step: put the bovine bone glue extract concentrate into a container, wherein the volume of the bovine bone glue extract concentrate is V1, the volume of the container is V2, V1: V2=20%; the bovine bone glue extract The moisture content of the concentrate is 70%;

[0044] refer to figure 1 , the container is a plastic tray 10 covered with a silicone sleeve 20.

[0045] 2) Vacuum drying steps:

[0046] 2-1) First put the container of step 1) into a static vacuum microwave dryer for preheating, so that the bovine bone glue extract concentrate is in a boiling state; control the boiling degree of the bovine bone glue extract concentrate by adjusting the vacuum degree to prevent bovine bone glue extract from boiling The bone glue extract concentrate boils and overflows the container, and the shrinkage liquid boils and overflows the container. Ad...

Embodiment 2

[0050] A vacuum low-temperature drying method for bovine bone glue, comprising the following steps:

[0051] 1) Raw material preparation step: put the bovine bone glue extract concentrate into a container, wherein the volume of the bovine bone glue extract concentrate is V1, the volume of the container is V2, V1: V2=15%; the bovine bone glue extract The water content of the concentrated solution is 70%; the container is a plastic plate covered with a silica gel sleeve.

Abstract

The invention discloses a vacuum low-temperature drying method for bovine bone glue, which comprises the following steps: 1) raw material preparation step: loading the concentrated bovine bone glue extract into a container, wherein the volume of the concentrated bovine bone glue extract is V1, and the container The volume is V2, V1: V2≤20%; 2) vacuum drying step: first the container of step 1) is put into microwave vacuum drying equipment and heated, so that the bovine bone glue extract concentrate is in a low-temperature boiling state; water vapor and The acetic acid vapor is sucked away by a vacuum pump, and the bovine bone glue extract is concentrated and dried to obtain the bovine bone glue. The vacuum low-temperature drying method of the invention has the characteristics of low acetic acid content, low energy consumption, short drying time, high product yield and high production efficiency.

Description

technical field [0001] The invention relates to a bovine bone glue, in particular to a vacuum low-temperature drying method for the bovine bone glue. Background technique [0002] Bovine bone glue is obtained from fresh bovine bone by extracting with acetic acid solution, degreasing, concentrating, drying, and pulverizing. The pharmacopoeia stipulates that the drying temperature of bovine bone glue should be below 100°C. [0003] The bovine bone glue drying method in the prior art is to dry the bovine bone glue extract concentrated solution with a water content of 70% into bovine bone glue with a water content of 12% by cooking in an open large pot or steam heating and drying in a vacuum tank. Because bovine bone glue contains a lot of collagen, after heating and boiling, a hard film will be formed on the surface of the extract, and the water and acetic acid are difficult to volatilize. It must go through a slow baking time, and sometimes it will be burnt, and The amount of...
