Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0018] The online wort cooling detection method of the portable dissolved oxygen meter of the present invention adopts the mobile cooler 3 and the portable dissolved oxygen meter 6 to perform online cooling detection of hot wort, in which:

[0019] 1. The mobile cooler 3 includes a cooling tube 10 (the cooling shell side of the mobile cooler 3) and a water tank 9. The cooling tube 10 is provided with a spiral tube 11 (the cooling tube side of the mobile cooler 3). The cooling pipe 10 is installed on the trolley plate frame 8 through a low bracket. The bottom of the trolley plate frame 8 is equipped with two sets of front and rear wheels. The water tank 9 is installed on the trolley plate frame 8 through a high frame and is located in the cooling pipe 10. Above the cooling pipe 2 is made of a sanitary pipe with a diameter greater than 20...

Abstract

The invention discloses a method for wort on-line cooling detection through a portable oxygen dissolving instrument. On-line cooling detection is conducted on hot wort through cooperation of a mobilecooler and the portable oxygen dissolving instrument, the method includes the three steps that hot wort sampling is conducted, specifically, a sampling valve is installed on a wort conveying pipelinein the hot wort section, a food grade rubber hose I communicates with the sampling valve and an inlet of the mobile cooler, and hot wort is introduced into the tube pass of the mobile cooler under thecondition of oxygen isolation; hot wort cooling is conducted, specifically, the hot wort is continuously precooled with low-temperature water with the temperature being 6 DEG C or below in the shellprocess of the mobile cooler; and cold wort detection is conducted, specifically, a food grade rubber hose II communicates with an outlet of the mobile cooler, after the hot wort is precooled to 40 DEG C or below, the sampling valve at the hot wort sampling point is closed and the portable oxygen dissolving instrument is started, the food grade rubber hose II is connected with the portable oxygendissolving instrument, then the sampling valve is opened, and on-line detection of cold wort oxygen dissolving is realized.

Description

Technical field [0001] The invention relates to a beer production inspection process, in particular to a portable dissolved oxygen meter wort online cooling detection method. Background technique [0002] At present, in order to control the oxygen content of the wort, some beer production plants need to use a portable dissolved oxygen meter to detect the oxygen content of the wort at different stages. However, the use of this portable dissolved oxygen meter to detect the wort has strict requirements: [0003] 1. Wort temperature is lower than 40℃. [0004] 2. The wort must be sealed before it enters the dissolved oxygen meter, and it must not be exposed to air. [0005] 3. In order to obtain the accurate value and analyze the trend of dissolved oxygen, it is necessary to carry out long-term testing according to the demand. [0006] However, the location span of the wort is relatively large in different process stages, and the wort temperature span is also large, ranging from 8°C to 100...
