产品说明：
JOYN品粗纤维测定仪是依据目前常用的酸碱消煮法消煮样品，并进行重量测定来得到试样的粗纤维含量的仪器。粗纤维测定仪采用浓度准确的酸和碱，在特定条件下消煮样品，再用乙醇除去可溶物质，经高温灼烧后扣除矿物质的量，所含量称粗纤维。粗纤维测定仪不是个确切的化学实体，只是在强制规定的条件下测出的概略成份，其中以纤维素为主，还有少量半纤维素和木质素。
产品特点：
1、粗纤维测定仪消煮装置采用陶瓷加热材料，热效能好，能充分获得消化效果。
2、所有浸提过程可通过自动放置阀操作，每个样品整套试验可单独操作。
3、内置蠕动泵,耐腐蚀，可气体反吹，加速洗涤效果。
4、粗纤维测定仪可配循环恒温水浴，进行高精度温度控制。
5、样品高度可升调节，方便取样放料。

Product description:
JOYN brａnd crude fiber tester is based on the currently used acid and alkali digestion method to boil the sample, and carry out weight measurement to obtain the crude fiber content of the sample. Crude fiber tester adopts acid and alkali with accurate concentration to eliminate boiled samples under specific conditions, and then USES ethanol to remove soluble substances, after being burned at high temperature, the amount of mineral is deducted, and the content is called crude fiber. The crude fibre tester is not an exact chemical entity, but is an overview of the components, mainly cellulose, with a small amount of hemicellulose and lignin, under generally accepted mandatory conditions.
Product features:
1. The crude fiber meter is made of high-quality ceramic heating materials, which has good thermal efficiency and can fully obtain the digestion effect.
2. All extraction processes can be operated through automatic valve placement, and each sample set can be operated separately.
3. Built-in inlet peristaltic pump is resistant to corrosion and can be blowback to accelerate the washing effect.
4. The crude fiber meter can be equipped with a circulating constant temperature water bath for high-precision temperature control.
5. The sample height can be upgraded and adjusted to facilitate sampling and discharging.
Technical parameters:
Crude fibre tester model: JOYN-CXW-6
Test object: the content of crude fiber in all kinds of grain, feed, grain, food and other agricultural and sideline products
Number of test samples: 6 / time
Repeatability error: crude fiber content is below 10%, absolute value error is not more than 0.4
The crude fiber content is more than 10%, and the relative error is less than 4%
Test time: about 90min on the instrument (including 30 minutes of acid, 30 minutes of alkali, about 30 minutes of filtration and washing)
Power supply: AC220V / 50 hz
Power: 3.3 KVA
Size: 540 * 450 * 670 mm
Weight of crude fibre tester: 28kg
