(3) product that step (2) the is obtained stoning of pulling an oar, and remove fructus corni through refiner, make the turbid juice that contains jujube meat enter surge tank;
(4) the turbid juice that step (3) is obtained carries out pasteurize, enzymolysis;
(5) the turbid juice that step (4) is obtained is transferred to extraction equipment through pump and extracts, and extract enters surge tank;
(6) extract that step (5) is obtained is transferred to ultrafiltration system and filters;
(7) the clear juice that step (6) is obtained is sent in the evaporimeter and is concentrated, and sends into the finished product jar when extract is concentrated into pol greater than 65 ° of BX;
(8) juice that step (7) is obtained carries out can after the pasteurize.
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the wooden jujube in the lixiviate jar in the step (2) and the weight ratio of water are 1: 3.
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein lixiviate jar temperature remains on 70 ℃ in the step (2).
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein turbid juice enters enzymatic vessel for 50 ℃-55 ℃ in temperature in the step (4).
Described a kind of method of producing jujube essence concentrated nutrient solution wherein adds the pectase of 50-100ppm in the step (4) in the enzymatic vessel, the enzyme time is 45 minutes.
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the ultrafiltration aperture is 0.1um in the step (6).
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein evaporating temperature is smaller or equal to 70 ℃ in the step (7).
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the sterilization temperature to pasteurization conduit and can head is 110 degree in the step (8), the time is 40 minutes.
Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the sterilization temperature in the step (4) is 90 ℃-95 ℃, the time was greater than 30 seconds.
After adopting such scheme, the present invention does not add any anticorrisive agent and other raw material because wooden jujube and pure water that employing is dried are raw material, has fully kept the natural nutrient component in the wooden jujube; Adopt in the processing to be lower than 70 ℃ of temperature extraction nutrient solutions, can make wooden jujube in extraction, avoid the infringement of high temperature, avoided conventional high-temperature to extract the burnt burning that is produced jujube nutrition; Adopt advanced enzymeization, separation, filtering technique can make product limpid bright, taste is purer, does not have precipitation, does not have macroscopic suspension and impurity; Adopt the vacuum concentration technique that product moisture is reduced, the product pol is more than or equal to 65 ° of BX, easier storage, and the storage life can reach 3 years; The independent separation of jujube nuclear, fructus corni, jujube meat helps the further development and use of jujube nuclear, fructus corni, jujube meat.
The specific embodiment
Embodiment 1
The wooden jujube that the present invention adopts maturation to dry is checked wooden jujube quality, weight, impurity, the source of factory, the wooden jujube planting base pollution-free, that use country to forbid agricultural chemicals of determining whether hang oneself raw material company's investigation determining.
The wood jujube cleans through water in tank, by elevator the wooden jujube in the tank is risen to and carries out the flushing of secondary water in second section Rinsing Area, and water for cleaning meets the GB5749 standard-required.
Wooden jujube transport tape after the cleaning is delivered to chooses the fruit platform, removes by choosing will go rotten rotten fruit and foreign material of fruit worker, and the wooden jujube after the selection enters rotary drum with conveyer belt and cleans.Clear water sprays the silt dirt in the further flush away wood jujube.
Wooden jujube lixiviate in the lixiviate jar of cleaning, earlier 70 ℃ of hot water are sent into the lixiviate jar during lixiviate, the wooden jujube of Xi Jinging is sent into the lixiviate jar by elevator then, the weight ratio of wood jujube and water is 1: 3, heat to material by steam during lixiviate, make extraction temperature remain on 70 ℃, 120 minutes time, diffusion water is to use the pure water of producing through the water-making machine group, this extracting technology adopts the continuous lixiviate mode of automation fully, extraction temperature, time, water and raw material weight all can be set in computer, and system finishes batching, insulation, lixiviate automatically according to setting.
The wood jujube is transferred to beater by centrifugal pump after lixiviate, remove jujube nuclear; Can separate fructus corni separately through the fructus corni separation equipment again; Separate jujube meat through jujube meat separation equipment again, the turbid juice that will contain jujube meat at last enters surge tank; Turbid juice is through preceding pasteurize, sterilization temperature is 90 ℃, and the time is greater than 30 seconds, enters enzymatic vessel after being cooled to 50 ℃, add pectase in the enzymatic vessel, carry out the enzyme processing, the pectase consumption is 60ppm, and the enzyme time is 45 minutes, turbid juice behind the enzymolysis is transferred to extraction equipment by pump and extracts, extraction equipment is to utilize action of centrifugal force, and jujube meat is separated with extract, and isolated extract enters surge tank.
