CN104026431A - Method for producing polycrystal rock sugar - Google Patents

Abstract

The invention discloses a method for producing polycrystal rock sugar, which relates to the edible sugar production field. The production method comprises the following steps: dissolving white sugar, adding sodium hydrosulfite, then filtering by using a screen mesh, placing in an jacketed kettle and concentrating for boiling sugar, removing the superfluous moisture, then naturally crystallizing, purging the crystallized semi-finished product polycrystal rock sugar, placing in a drying house for drying, fragmenting, and packing the produced polycrystal rock sugar. The production method has the advantages of simple preparation technology and high crystallization rate, and the product prescription can reach a uniform standard.

Description

The manufacture method of polycrystalline rock sugar

Technical field

The present invention relates to table sugar production field, especially a kind of manufacture method of polycrystalline rock sugar.

Background technology

Rock sugar has two kinds, monocrystal rock sugar and polycrystalline rock sugar.Rock sugar is transparent or semitransparent shape; Rock sugar taste is sweet, have tonifying middle-Jiao and Qi, Yin-nourishing and body fluid promoting, moisten the lung and relieve the cough, turbid effect falls in clearing heat and detoxicating, beauty treatment, relieve sore throat, phlegm profit larynx, tasty and refreshing appetizing clearly, benefit diseases such as controlling pharyngalgia dry, hypertension, in many countries, using rock sugar as the good medicine of curing cold, be generally subject to liking of consumer.

The manufacturing technology of polycrystalline rock sugar is ripe known technology, but ingot is tiny, transparency is not high, and product specification does not reach unified standard.

Summary of the invention

Problem to be solved by this invention is to provide the manufacture method that a kind of ingot is large, product regulation reaches the polycrystalline rock sugar of unified standard.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is that its manufacturing step is:

White granulated sugar is put into sugar dissolver, add 25% water, with high-temperature steam, be heated to dissolve;

2), after sugar dissolves, add sodium dithionite, 0.003% of sodium dithionite addition≤white granulated sugar gross weight;

3), sodium dithionite fully mixes and dissolves by screen filtration with white granulated sugar, not tolerant the filtering out in the liquid glucose dissolving;

4), the liquid glucose after filtering is transported to jacketed pan, and to boil sugar concentrated, and the excessive moisture in liquid glucose is removed, it is 113 ℃-118 ℃ that molasses are boiled to temperature;

5), well-done liquid glucose is packed in rock sugar bucket and is placed on insulated building, at room temperature carry out spontaneous nucleation, crystallization time is 7 days;

6), rock sugar honey is removed after, the rock sugar of advantages of good crystallization is placed on the sugared frame that dries in the air and is dried in the air 24 hours under normal temperature;

7), take out rock sugar bucket, semi-finished product rock sugar is sent into drying room and dries, drying room temperature is 60-70 degree, drying time 19 hours-21 hours;

8), the rock sugar after drying is broken into blocky-shaped particle of uniform size, the sale of can packing.

In technique scheme, scheme can also be more specifically: described 3) in step, screen cloth is 80 orders.

Owing to adopting above-mentioned manufacture method, the present invention has following beneficial effect:

The polycrystalline rock sugar preparation technology that the present invention manufactures is simple, and percent crystallization in massecuite is high, ingot is large, product regulation reaches unified standard.

The specific embodiment

Below in conjunction with example, the invention will be further described:

The manufacture method of the polycrystalline rock sugar of the present embodiment, its manufacturing step is:

1), 1000 kilograms of white granulated sugars are put into sugar dissolver, add the water of 250 kilograms, with high-temperature steam, be heated to dissolve;

2), after sugar dissolves, add sodium dithionite, add the sodium dithionite of 0.03 kilogram;

3), sodium dithionite fully mixes and dissolves by 80 object screen filtrations with white granulated sugar, not tolerant the filtering out in the liquid glucose melting;

4), the liquid glucose after filtering is transported to jacketed pan, and to boil sugar concentrated, and the excessive moisture in liquid glucose is removed, it is 113 ℃-118 ℃ that molasses are boiled to temperature;

5), well-done liquid glucose is packed in rock sugar bucket and is placed on insulated building, control insulated building temperature, at room temperature carry out spontaneous nucleation, crystallization time is 7 days;

6), rock sugar honey is removed after, the rock sugar of advantages of good crystallization is placed on the sugared frame that dries in the air and is dried in the air 24 hours under normal temperature;

7), take out rock sugar bucket, semi-finished product rock sugar is sent into drying room and dries, drying room temperature is 60 degree, drying time is 20 hours;

8), the rock sugar after drying is broken into blocky-shaped particle of uniform size, can pack, reviewer's requirement in accordance with regulations, carries out sampling inspection to finished product, and sale is up to the standards; Packaging bag use before with ultraviolet disinfection, guarantee that sealing is non-off-line, sealing compound does not come off after packing rock sugar into.
