Abstract
The present invention relates to a new juicing technology for a belt pressing machine, which comprises processes of fruit paste preparation, one-grade pressing, two-grade pressing and three-grade pressing. After two-grade pressing the fruit residue is well mixed with water according to a weight ratio between 1 to 0.8 with 1 to 1.2, followed by standing for 20 to 60 minutes. The mixture is then sent into the two-grade belt pressing machine for the third pressing. The fruit juice isolated from three-grade pressing is then mixed with the fruit residue from the first pressing. The invention is capable of sufficiently extracting the sugar content from the raw material of kernel fruit as well as reducing fruit loss ratio of the product. In addition, the final product quality is similar to the prior two pressing technology, which also effectively improves production efficiency of the fruit processing.
Description
Technical field
The present invention relates to a kind of technology of squeezing the juice, relate in particular to a kind of new technology of squeezing the juice of belt-style press machine, it is applicable to pomaceous fruit fruit raw material, as apple, pears, hawthorn etc., and the processing technology of squeezing the juice from pulp in the broken back of selection.
Background technology
Squeezing the juice is the core process that fruit juice is produced, and the juice extractor performance directly influences and determining product quality and cost.Common juice extractor has the conspicuous juice extractor of cloth, belt-style press machine etc.The belt-style press machine is used widely in China in recent years, and it has characteristics such as simple in structure, that work is continuous, productivity ratio is high, power consumption is low, versatility is good, cost is moderate, can make more than the bandwidth 2m ultra-large type juice extractor that disposal ability 20t/h is above.It is about 0.3MPa that the belt-style press machine is stuck with paste the maximum squeeze force that produces to fruit, adopt the crushing juice rate of common band compression technology processing fresh apple can reach more than 75%, adopt the extracting technology crushing juice rate can reach more than 85%, therefore, the belt-style press machine is the normal equipment of squeezing the juice that adopts of large and medium-sized fruit juice processing factory.But (it is believed that usually as three squeezings then can lose more than gain twice squeezing of the many employings of existing belt press production technology, as increase that energy consumption, fruit juice pol reduce, degradation under the product quality), and the fruit loss-rate of this production technology is higher, and fruit resource utilization very insufficient (very high as the sugar in the pomace of discharging).Though the conspicuous juice extractor of cloth is higher than belt-style press machine to the utilization rate of fruit, (the import equipment but it costs an arm and a leg, price is higher than 3～5 times of home equipments), most producers hang back, but also exist batch press, the easy brown stain of fruit juice, only be suitable for producing shortcomings such as clear juice, this juice extractor short time is difficult to be popularized.Therefore, must be based on most producers having production equipment (belt-style press machine) is carried out the improvement of production technology aspect.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of fruit loss-rate belt-style press machine low, that can make full use of fruit resource new technology of squeezing the juice.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of belt-style press machine new technology of squeezing the juice, referring to Fig. 1, it comprises the steps:
(1) the pulp preparation is broken for pulp after the fruit of select is cleaned;
(2) the one-level squeezing is sent pulp into first order belt-style press machine and is squeezed the juice separation fruit juice and pomace;
(3) secondary squeezing one-level is squeezed isolated pomace and is sent into secondary belt-style press machine and squeeze, and separates fruit juice;
(4) three grades of squeezings pomace after through the secondarys squeezing is with pomace: the part by weight of water=1: 0.8～1.2 left standstill 20～60 minutes after adding the water mixing, sending into three grades of belt-style press machines again squeezes for the third time, pomace after isolated fruit juice and the squeezing for the first time mixes mutually, and isolated pomace is discharged and handles after three grades of squeezings.
In the shattering process of described step (1) fruit,, again pulp is put in the pulp jar and kept in 20～60 minutes with pulp enzyme 30～70ml/ ton pulp.
In described step (2), one-level is squeezed isolated pomace and is mixed lixiviate after 20～60 minutes with three grades of isolated fruit juice of squeezing with the weight ratio of 1:0.8～1.2, carries out the squeezing second time again.
Squeeze to one-level isolated pomace add three grades the squeezing isolated fruit juice in, with pulp enzyme 50ml/ ton pomace.
The present invention has actively useful effect:
1. fully extract the sugar in the pomaceous fruit fruit raw material, reduced really consumption.Go pomace after lixiviate is squeezed for the first time with the fruit juice that squeezes out for the third time, do not increase under the prerequisite of the water yield, improve the discharging pol of second level press juice, reduced the pol of discharging in the pomace to greatest extent, the maximum that realizes fructose reclaims, thereby has reduced really consumption.The engineer testing that with the apple is raw material shows: with two press the technologies contrast, final deslagging pol drops to 2.30BX by original 4.60BX; Two squeezed juice pols have improved 1.50BX; The average pol of ultrafiltration has improved 0.50BX.Two press technology fruit unit consumption 1:7.11 (1 ton of inspissated juice of every product needs 7.11 tons of fruits), and three press technology fruit unit consumption 1:6.61 (1 ton of inspissated juice of every product needs 6.61 tons of fruits), reduce by 0.5 point.From data analysis as can be seen, three press technology can make raw material consumption reduce by 0.5 point at least, is equivalent to one ton of finished product of every production, and raw material consumes 500Kg less.
2. end product quality is identical with former two press for extracting juice technologies.Detect with combining completely as fumaric acid, the finished product index do not occur influencing; The other products index is pressed technology than two and is not found notable difference; Evaporimeter is owing to the rising of material pol, and the production capacity performance is pressed technologies than two and increased.
3. productivity effect improves.Now illustrate, compare with former secondary squeezing process, these three grades of squeezing process need increase one of belt press newly, count 950,000 yuan, 120,000 yuan of two screw pumps, 7.5 ten thousand yuan in pulp jar, 20,000 yuan in pipeline etc., construct the factory buildings 4.5 ten thousand yuan: 72.5 degree/hour * 0.6 yuan/spend * 20 hours/day * 26 days/month * March/year=6.7860 ten thousand yuan, water: recycling.The newly-increased input amounts to: 127.786 ten thousand yuan.
Through measuring and calculating, squeeze the juice and can improve 3 ° of Bx of pol in three press for extracting juice backs three, article two, handle the production line of 20 tons/hour of apples, can produce 10 tons/hour of pomaces, if the pol of inspissated juice finished product per ton is 70.5 ° of Bx, per hour can increase carry pol be 10 tons * 3 ° Bx/70.5 ° of Bx=0.425 tons/hour finished product, if inspissated juice price per ton is 12000 yuan/ton, can per hour can increase by 0.425 ton/hour * 12000 yuan/ton=5100 yuan/hour of benefits.Produced every day 20 hours, produced 26 days in every month, annual production 3 months then can increase benefit in 1 year: 5100 yuan/hour * 20 hours/day * 26 days/month * March/year=795.6 ten thousand yuan/year.
This shows that though increase one-level squeezing energy consumption and equipment investment increase to some extent, the fruit loss-rate reduces, the finished product pol increases, and has saved the fruit raw material greatly, more than is example, and year has a net increase of net income and can reach 667.8 ten thousand yuan, and productivity effect obviously increases.
