Example Embodiment

[0026] The preparation method of described hop extract feed additive comprises the following steps:

[0027] (1) The hops are crushed by a grinder, sieved, and then put into the extraction kettle; the sieve sieve diameter can be 2.0mm;

[0028] (2) From CO 2 CO out of cylinder 2 gas, CO 2 The gas is cooled to a liquid by the liquefier, and the CO 2 The liquid is pressurized to 15~30 MPa by a high-pressure metering pump, and then heated to 35~50°C by a heater, and then it enters the extraction kettle to extract the hop powder. The extraction time is 2~4 h, CO 2 The flow rate is 25~30 L / h, and the CO with hop active ingredient is dissolved. 2 liquid;

[0029] (3) CO dissolved in active ingredients of hops 2 The liquid enters the separation device through the pressure reducing valve for separation, and the active ingredients of hops are separated out to obtain a paste-like hops extract;

[0030] (4) Mixing and stirring the above hop extract, licorice powder and corn cob po...

Example Embodiment

[0036] Example 1

[0037] The granular hops were pulverized and sieved to obtain hop powder with a particle size of 400-500 μm. The effective active ingredients and contents were determined to be: α-acid 5.21, β-acid 6.75; 5.00 g of hop powder was accurately weighed and placed in In the extraction kettle, from CO 2 CO2 gas flows out of the cylinder, CO 2 The gas is cooled to liquid by the liquefier; the CO 2 The liquid is pressurized to 25 MPa by a high-pressure metering pump; 2 Heated to 45°C by heater; liquid CO 2 into the extraction kettle for extraction, the extraction time is 3 h, CO 2The flow rate is 27L / h; the CO dissolved with the active ingredients of hops 2 Enter the separation device through a pressure reducing valve for separation, wherein the separation device is composed of a first separation tank and a second separation tank, the pressure in the first separation tank is 15Mpa, and the temperature is 40 °C; the pressure in the second separation tank is 6 MP...

Abstract

The invention discloses a Humulus lupulus extract feed additive and a preparation method thereof. The Humulus lupulusHumulus lupulus extract feed additive is prepared from the following components in parts by weight: 20-50 parts of Humulus lupulus extract, 20-30 parts of liquorice powder and 20-60 parts of corncob powder. Compared with the prior art, the invention has the following advantages: 1,supercritical CO2 extraction is adopted to effectively remove pungent smell of Humulus lupulus and maintain effective contents to the hilt at the same time, wherein beta acid and alpha acid in the Humulus lupulus extract are main active substances, and liquorice, with harmonic function, can be compatible with the Humulus lupulus extract to improve the efficiency of Humulus lupulus; 2, the feed additive provided by the invention is solid, thereby having the advantages of being convenient to store, transport and add; 3, the product provided by the invention can improve the organism health condition, improve the immunity of the organism, reduce the feed conversion ratio, and has importance to development of animal husbandry, promotes the coming of 'antibiotic reduction, zero antibiotic'; besides, the application range of Humulus lupulus is widened, and the feed additive has important significance to healthy development of Humulus lupulus planting industry.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a hop extract feed additive and a preparation method thereof. Background technique [0002] Hops, whose scientific name is Humulus Lupulus L, can also be called famous hops, hops, wild hops, hops, yeast flowers, arabesque flowers, hop flowers, etc., which are dioecious winding herbaceous plants. Hops are mainly distributed between 35° and 55° north and south latitudes, and are mainly produced in Britain, Denmark, Ireland, France in Europe, Turkey in Asia, China and the United States in North America. Hops are cultivated in North China, Northeast China, and Northwest China. In Northwest China, hops are mainly distributed in Xinjiang and the Hexi Corridor in Gansu. The hop production in these two areas accounts for 95% of my country's total output. [0003] Hops are one of the essential raw materials for the beer industry, indispensable and irreplaceable in beer brewing. S...
