食用菌无尘车间南北通风有什么差异?

来源:http://www.henganjh.cn │ 发表时间:2019-05-20 

  食用菌山东无尘车间南北方通风的差异
  Difference of ventilation between North and south of edible fungi dustless workshop in Shandong Province在食用菌无尘无菌车间生产中,培养室和出菇房都需要根据蘑菇的生长需要进行通风换气,进入室外新鲜的空气,排出蘑菇生长产生的二氧化碳。
  In the production of edible fungi dust-free aseptic workshop, the cultivation room and mushroom production room need ventilation according to the mushroom growth needs, entering fresh outdoor air, discharging the carbon dioxide produced by mushroom growth.
  进入菇房的空气温度和湿度,会对菇房的温度和湿度产生很大的影响,室内外的差距越大,通风就更容易造成房间的环境不稳定。
  The air temperature and humidity entering the mushroom house will have a great impact on the temperature and humidity of the mushroom house. The larger the gap between indoor and outdoor, the more likely the ventilation will cause the unstable environment of the room.
  在南方,夏季室外空气相对湿度较大,通风会导致菇房湿度上升,加上大多数食用菌生长温度都低于外界温度很多,高温、高湿的室外空气进入菇房会产生冷凝现象,墙壁、库板表面出现的冷凝水会滋生细菌和霉菌。
  In the south, the relative humidity of outdoor air is relatively high in summer. Ventilation will cause the humidity of mushroom house to rise. In addition, the growth temperature of most edible fungi is much lower than the outside temperature. When high temperature and humidity outdoor air enters mushroom house, it will produce condensation phenomenon. The condensation water on the surface of walls and warehouses will breed bacteria and fungi.
  如果这种情况出现在接种室、培养室等前段环节,就容易导致污染率上升。如果出现在出菇房,会导致蘑菇干度下降,影响货架期,甚至严重的病害。
  If this situation occurs in the vaccination room, culture room and other front links, it will easily lead to increased pollution rate. If it appears in the mushroom room, it will cause the dryness of mushrooms to decline, affect the shelf life, and even serious diseases.
  南方食用菌无菌厂房在夏季,净化车间应该减少外循环新风的风量,或者全部处于内循环状态,比较大限度的避免室外高温、高湿空气的进入。培养房和出菇房在设计方案时就应该考虑到新风降温、降湿的问题,如果采用集中送风比较容易解决,在新风机加装表冷器,表冷器通入低温的载冷剂。
  In the South edible fungi sterile workshop in summer, the purifying workshop should reduce the outdoor fresh air flow, or all in the internal circulation state, to avoid the entry of outdoor high temperature and humid air to the greatest extent. In the design of the cultivation room and mushroom production room, the problem of fresh air cooling and humidity reduction should be taken into account. If centralized air supply is easier to solve, the surface cooler is added to the fresh air fan, and the surface cooler is fed into the cryogenic refrigerant.
  在北方,夏季高温对通风的影响只在夏季温度比较高的一段时间出现,而且影响远没有南方大。
  In the north, the influence of high temperature in summer on ventilation only occurs during the period of the highest temperature in summer, and the influence is far less than that in the south.
  在北方,通风对食用菌生产的影响是在冬季,室外空气的特征是低温和干燥,低温和干燥的空气对冷却室、接种室没有明显的影响。对培养室和出菇房影响很大,主要表现在两点,一是低温的空气进入会造成培养室部分区域因新风而降低温度,进而导致发菌和出菇的不一致性。二是低湿干燥的空气会瞬间将菇房相对湿度将至不可接受的程度。
  In the north, the influence of ventilation on the production of edible fungi is in winter. Outdoor air is characterized by low temperature and dryness. Low temperature and dry air have no obvious influence on cooling room and inoculation room. It has a great influence on the culture room and mushroom production room, mainly in two aspects. First, low temperature air entering the culture room will cause some areas of the culture room to lower temperature due to fresh air, which will lead to the inconsistency between Germination and mushroom production. Second, low humidity and dry air will instantly make the relative humidity of mushroom house unacceptable.

  对于新风温度低,比较好的解决办法是进行新风预热,同样,集中送风比较容易解决,在新风机内部加装预热装置,如果条件允许,新风温度进行自动控制。
  For the low temperature of fresh air, the best solution is to preheat the fresh air. Similarly, centralized air supply is easier to solve. A preheating device is installed inside the fresh air fan. If conditions permit, the fresh air temperature is automatically controlled.
  在北方,冬季新风温度低可以通过预热的方式解决,但是新风湿度小就没有办法通过预湿的方法解决了,主要是湿度大小不容易控制,通风管道加湿后容易滋生细菌等无法解决。
  In the north, the low temperature of fresh air in winter can be solved by preheating, but the low degree of new rheumatism can not be solved by prewetting. The main problem is that the humidity is not easy to control, and the bacteria are easy to grow after humidifying ventilation ducts.
  因此,北方食用菌生产在冬季应该特别注意新风湿度小对环境产生的影响,提前检修加湿设备,配备足够的加湿量,有条件必须采用超声波加湿器。
  Therefore, the production of edible fungi in northern China should pay special attention to the impact of low rheumatism on the environment in winter. The humidifier should be repaired in advance, equipped with adequate humidification, and the ultrasonic humidifier must be used when conditions permit.
  在换风前,菇房的湿度要为换风留出适当的余量,抵抗新风干燥对菇房环境的冲击,采用少通风、勤通风的原则。
  Before ventilation, the humidity of mushroom house should set aside appropriate allowance for ventilation, resist the impact of fresh air drying on the environment of mushroom house, and adopt the principle of less ventilation and frequent ventilation.
  冬季北方菇房的排风口容易出现冷风倒灌的现象,会导致菇房内部排风口附近温度长时间偏低,一般会在排风口安装止回装置,但是作用不大,只是减少影响。
  In winter, cold air backfilling is easy to occur in the vents of mushroom houses in northern China, which will cause the temperature near the vents of mushroom houses to be low for a long time. Generally, check devices will be installed in the vents, but the effect is not significant, but only to reduce the impact.
  无尘车间温湿度调节、测试方法
  Temperature and Humidity Regulation and Test Method in Dustless Workshop无尘车间的温度测试有功能温度测试和一般温度测试。功能温度测试主要用于无尘车间需严格控制温度精度时或建设方要求在“静态”或“动态”进行测试时应用;一般温度测试主要使用于“空态”时温度测试。
  The temperature test in dust-free workshop includes functional temperature test and general temperature test. Functional temperature testing is mainly used in dust-free workshop when temperature accuracy is strictly controlled or when the builder requires it to be used in "static" or "dynamic" testing; general temperature testing is mainly used in "empty" temperature testing.
  无尘车间功能温度测试,应将洁净区划分为等面积的栅格,每个分格面积不超过100平方米或与建设方协商确定,每格测点1个以上,每个房间测点至少2个。测试高度应为工作面高度,距的吊顶、墙面和地面不小于300MM,并应考虑热源等的影响,测量时间应至少1H,并至少6min测量一次,读数稳定后做好记录。无尘车间一般温度测试的测点,每个温度控制区或每个房间1个测点,测试点高度宜为工作面高度,测量时间应至少1H,并至少6min测量一次,读数稳定后做好记录。
  In the functional temperature test of dust-free workshop, the clean area should be divided into equal-area grids. Each grid area should not exceed 100 square meters or be determined by consultation with the builder. There are more than one measuring point per grid and at least two measuring points per room. The test height should be the height of the working face, not less than 300MM from the ceiling, wall and ground, and the influence of heat source should be taken into account. The measurement time should be at least 1H, and at least 6min. After reading is stable, the record should be made. General temperature test points in dust-free workshop, one test point in each temperature control area or room, the height of test points should be the height of working face, the measurement time should be at least 1H, and at least 6 minutes to measure once, after reading is stable, record well.
  无尘车间湿度测试:湿度测试可采用通风干湿球湿度计、电容式湿度计、数字式湿度计、毛发式湿度仪器。
  Dustless workshop humidity test: humidity test can use ventilated wet bulb humidity meter, capacitive humidity meter, digital humidity meter, hair humidity instrument.
