CN104875929A - Non-pasteurization sterile filling method for concentrated clear juice - Google Patents

Abstract

The invention discloses a non-pasteurization sterile filling method for concentrated clear juice. The non-pasteurization sterile filling method comprises the following steps of adding a paperboard filler between a finished product can and a filling machine during processing of concentrated juice; sterilizing non-pasteurization sterile temporarily stored concentrated clear juice of the finished product can through the paperboard filter of which a paperboard has the size of 0.2 micrometer; carrying out sterile filling of the concentrated clear juice; performing steam sterilization and disinfection on the paperboard filter before filling; connecting pipelines of the filling machine; and performing filling after performing CIP cleaning and sterilization on the filling machine. Filled finished products are in a commercial sterilization state, the circumstance that the juice is sterilized and is filled after being cooled down is avoided, non-sterile juice can be subjected sterile filling directly without high-temperature sterilization, and a filling procedure between the finished product can and the filling machine is omitted; and high-temperature sterilization is omitted, loss of nutritional ingredients of the juice and negative effects on flavor and color value of the juice are reduced, and energy consumption in a filling process is reduced.

Description

A kind of concentrated non-bar of clear juice kills aseptic filling method

Technical field

The present invention relates to fruit juice production technical field, a kind of concentrated non-bar of clear juice kills aseptic filling technology specifically, obtains finished product after namely having bacterium fruit juice at room temperature to carry out sterile filling after cardboard filter is degerming, does not need after high temperature sterilization cooling filling.

Background technology

Concentrated clear juice is the main processing variety of fruit, the filling inspissated juice of sterile filling technique is generally adopted in current fruit juice industry, and according to the different requirements of client to acidity, colour, often relate to concentrated clear juice and mix the problem converted, and mixed converting can not guarantee to carry out under sterile working.Existing concentrated clear juice filling process is: evaporator concentrates (or directly mixing at finished pot the fruit juice converted)----finished pot is non-sterile temporary----filter----sterilization (>=98 DEG C, >=30s)----being cooled to room temperature----filling head sterile filling is to sterile bag, technological process more complicated, wherein high temperature sterilization step fruit juice colour reduces 4%(T440nm) more than, lose the nutritional labeling of fruit juice simultaneously, affect good flavor, add energy consumption, improve cost of product.

Summary of the invention

The object of the invention is the deficiency overcoming above-mentioned prior art, there is provided a kind of concentrated non-bar of clear juice to kill aseptic filling method, mainly solve existing sterile filling technique or fruit juice is mixed when converting filling loss juice nutrient ingredient, affect good flavor, reduce fruit juice colour, the problem such as energy consumption is high, tooling cost is high, microbiological contamination probability height.

In order to achieve the above object, the present invention is achieved in that a kind of concentrated non-bar of clear juice kills aseptic filling method, comprises the following steps: the pipeline of (1), on a production line finished pot and bottle placer installs cardboard filter degerming;

(2), cardboard filter is carried out steam sterilization sterilization;

(3), by finished pot, connecting line, bottle placer clean through conventional CIP, after water rinses, emptying, valve-off, stand-by;

(4) the concentrated clear juice that manufacturing line is processed through enrichment process pumps into finished pot and keeps in after cooling;

(5), by the inspissated juice in step (4) pump into cardboard filter to filter, the aseptic pipeline under room temperature after sterilization, filling by filling, obtain finished product.

Preferably, described cardboard filter paper using panel aperture≤0.2um.

The concentrated non-bar of clear juice of the present invention kills aseptic filling method and compared with the prior art has outstanding substantive distinguishing features and marked improvement: high temperature sterilization (>=98 DEG C together with 1, decreasing, >=30s) and refrigerating work procedure, the non-bar achieving concentrated apple juice kills sterile filling, reduce energy consumption and tooling cost, remain the nutritional labeling of fruit juice largely, maintain the local flavor of fruit juice, fruit juice colour; 2, reduce juice browning amplitude, fruit juice colour is no longer because high temperature sterilization reduces at least 4%(T440nm), be conducive to producing high color value fruit juice; 3, instead of the filter progress of finished pot and bottle placer, and effectively can remove foreign matter; 4, because adopting the cardboard of 0.2um to filter, can clarify further concentrated clear juice, reducing the turbidity of fruit juice, reduce the risk of fruit juice poor stability (by GB/T18963-2012 test), improve product quality, reduce energy consumption and tooling cost.

Detailed description of the invention

In order to Comprehension and Implementation better, describe the present invention in detail below in conjunction with embodiment.

Embodiment 1: the cardboard filter 245 finished pots on a production line and the pipeline of bottle placer being installed 0.2um, cardboard filter is carried out steam sterilization, finished pot, connecting line and bottle placer clean through conventional CIP, after water rinses, emptying, valve-off, stand-by;

Manufacturing line is pumped into above-mentioned 245 tons of finished pots through the concentrated clear juice that enrichment process is processed after cooling keep in, pump into cardboard filter and filter, the aseptic pipeline under room temperature after sterilization, filling by filling, obtain finished product.

Embodiment 2: the cardboard filter 245 finished pots on a production line and the pipeline of bottle placer being installed 0.2um, after just cardboard filter carries out that steam sterilization, finished pot, connecting line and bottle placer clean through conventional CIP, water rinses, emptying, valve-off, stand-by;

Concentrated evaporator supplypump will be converted enter after above-mentioned 245 tons of finished pots mix until mixed, and pump into cardboard filter and filter, the aseptic pipeline under room temperature after sterilization, filling by filling, obtain finished product.

Claims (2)

1. the concentrated non-bar of clear juice kills an aseptic filling method, it is characterized in that comprising the following steps: the pipeline of (1), on a production line finished pot and bottle placer installs cardboard filter degerming;

(2), cardboard filter is carried out steam sterilization sterilization;

(3), by finished pot, connecting line, bottle placer clean through conventional CIP, after water rinses, emptying, valve-off, stand-by;

(4) the concentrated clear juice that manufacturing line is processed through enrichment process pumps into finished pot and keeps in after cooling;
