Description

A kind of tea seed essence production technology

Technical field

The invention belongs to tea seed processing technique fields, and in particular to a kind of tea seed essence production technology.

Background technique

China is the maximum country of tea-oil tree yield, there are about 3,670,000 hectares of oil tea resource, produces 64.5 ten thousand tons of oil tea seed per year. Tea seed essence is present in tea seed and squeezes except the tea seed grouts that in residual residue cake of camellia oleifera seeds, annual 400000 tons or so of China after grease It is thrown away, a considerable amount of tea seed essence is discarded, and causes greatly to waste.

Tea seed essence is jolted and is shaken, be easy to produce carbon dioxide due to long-distance transportation, and flatulence, existing tea seed essence are caused Production in material utilization it is lower, there is pollution in production process, sustainable productivity is lower.

Summary of the invention

The purpose of the present invention is to provide a kind of tea seed essence production technologies, to solve mentioned above in the background art ask Topic.

To achieve the above object, the invention provides the following technical scheme: a kind of tea seed essence production technology, including following step It is rapid:

S1, leached tea oil slag is crushed, smashed leached tea oil slag powder is put into infuser, is extracted with methanol, uses dish After piece centrifuge isolates tea grounds, extraction mixed liquor is obtained；

The wet dregs of rice are delivered in desolventizing machine through wet dregs of rice scraper plate pipeline in S2, infuser, and prolapse solvent is sent into condenser, are then sent Enter Methanol Recovery week stock relocation carry out Methanol Recovery, Methanol Recovery week stock relocation communicated with methanol library, dregs of rice slag through the dregs of rice slag pipeline entrance It is dried in dryer；

S3, mixed liquor is extracted in infuser when reaching 5 Baume degrees, filtered twice, be re-fed into the first long-tube evaporator and steam Hair, until the evaporation of the second long-tube evaporator is re-fed into when 8 Baume degrees, until 12 Baume degrees, are re-fed into multiple groups single-effect concentrator and carry out Concentration, is concentrated into 25 to 26 Baume degrees；

S4, after being concentrated by multiple groups single-effect concentrator, it is sent into hold-up tank, 0.3% Kathon CG is added to get smart to tea seed.

Preferably, it is 90% that extraction methanol concentration is carried out in step S1, and extraction is heated to reflux in 50 DEG C of hot bath 3-4h。

Preferably, the first long-tube evaporator operating pressure is 0.4-0.5mpa in step S3, and extraction mixeding liquid temperature is 90- 100 degree.

Preferably, the second long-tube evaporator operating pressure is 0.3 to 0.4mpa in step S3, and extraction mixeding liquid temperature is 85 To 95 degree.

Preferably, multiple groups single-effect concentrator operating pressure is 0.1-0.2mpa in step S3, and extraction mixeding liquid temperature is 80- 90 degree.

Preferably, the first long-tube evaporator, the second long-tube evaporator, multiple groups single-effect concentrator, desolventizing machine and dryer make It is energized with steam boiler, steam boiler generates steam and carries out condensed water water circulation through condenser, cooling tower, circulating water pool.

Technical effect and advantage of the invention: the tea seed essence production technology, the addition of Kathon CG are solved since long range is transported It is defeated, it jolts and shakes, make the vegetable protein and polysaccharide in tea seed essence, generate carbon dioxide under force, cause flatulence Problem, can also play prevents albumen and polysaccharide from fermenting under the action of alien bacteria and leading to the problem of carbon dioxide, environmental protection Nuisanceless, no chemical reaction is generated with waste water, obtains steam by biomass fuel, meets the requirement of environmental protection production, technique Leftover bits and pieces after precipitation, drying are used as biological organic fertilizer, realize the saving of resource and recycle, entire production process, chain It connects completely, can be used with popularity.

Detailed description of the invention

Fig. 1 is process flow chart of the invention.

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

The present invention provides a kind of tea seed essence production technologies as shown in Figure 1, comprising the following steps:

S1, leached tea oil slag is crushed, smashed leached tea oil slag powder is put into infuser (can also wherein contain a small amount of straw), is used Methanol is extracted, extraction with methanol concentration be 90%, be heated to reflux in 50 DEG C of hot bath extraction 3-4h, using disk from After tea grounds is isolated in scheming, extraction mixed liquor is obtained；

The wet dregs of rice are delivered in desolventizing machine through wet dregs of rice scraper plate pipeline in S2, infuser, and prolapse solvent is sent into condenser, are then sent Enter Methanol Recovery week stock relocation and carry out Methanol Recovery, Methanol Recovery technology is more mature, Methanol Recovery week stock relocation and methanol library It communicates, dregs of rice slag enters in dryer through dregs of rice slag pipeline is dried, and the leftover bits and pieces after precipitation may be used as giving birth to after drying Organic fertilizer is the first-class organic fertilizer of nuisanceless and organic agricultural fruits and vegetables；

S3, mixed liquor is extracted in infuser when reaching 5 Baume degrees, filtered twice, be re-fed into the first long-tube evaporator and steam Hair, the first long-tube evaporator operating pressure are 0.4-0.5mpa, and extraction mixeding liquid temperature is 90-100 degree, until when 8 Baume degrees, then It is sent into the evaporation of the second long-tube evaporator, the second long-tube evaporator operating pressure is 0.3 to 0.4mpa, and extraction mixeding liquid temperature is 85 To 95 degree, until 12 Baume degrees, are re-fed into multiple groups single-effect concentrator and are concentrated, multiple groups single-effect concentrator operating pressure is 0.1- 0.2mpa, extraction mixeding liquid temperature are 80-90 degree, are concentrated into 25 to 26 Baume degrees；

S4, after being concentrated by multiple groups single-effect concentrator, it is sent into hold-up tank, 0.3% Kathon CG is added to get to tea seed essence, adds Add Kathon CG mainly to solve to jolt and shake due to long-distance transportation, makes the vegetable protein and polysaccharide in tea seed essence, in the work of power With lower generation carbon dioxide, the problem of causing flatulence, a small amount of Kathon CG is added, effectively inhibits the generation of carbon dioxide, can also rise Carbon dioxide is generated to preventing albumen and polysaccharide from generating physical change (commonly referred to as ferment) under the action of alien bacteria.

Specifically, the first long-tube evaporator, the second long-tube evaporator, multiple groups single-effect concentrator, desolventizing machine and dryer make It is energized with steam boiler, obtains steam with biomass fuel, follow green, environmental protection, non-harmful production theory, steam Boiler generates steam and carries out condensed water water circulation through condenser, cooling tower, circulating water pool.
