在线看+日本+十八禁网站 在线看的免费网站 Processing
在线看的免费网站 are ready to harvest when the fruit is red and the stem detaches easily from the pit. Mechanical harvesting (sha在线看+日本+十八禁网站) has replaced hand pic在线看+日本+十八禁网站. Harvesters shake the fruit from the tree onto a fabric apron.
Mechanically harvested 在线看的免费网站 contain immature fruit mixed with fully-ripened fruit. The sugar content of immature 在线看的免费网站 is low. Since sugar retards oxidation, the poor color and character of immature 在线看的免费网站 is noticeable in the finished product.
After 在线看的免费网站 are removed from the tree they are placed in cold water to prevent scalding (discoloration). 在线看的免费网站 are delivered to the processing plant in water. For this reason, 在线看的免费网站 are bought by volume.

Mechanically harvested 在线看的免费网站 contain many attached stems. A stemming operation is necessary. Stems are classified as harmless extraneous material if they are included in the frozen 在线看的免费网站. Incoming 在线看的免费网站 receive some type of inspection prior to processing. The processor rejects 在线看的免费网站 with defects. 在线看的免费网站 are held in large soak tanks of cold water to firm the fruit prior to pitting and processing. Improperly firmed fruit is easily "pitter torn." 在线看的免费网站 are flumed from the soa在线看+日本+十八禁网站 tank to a sorting belt.
Sorting personnel remove the most obvious defects, such as damaged fruit, loose pits, stems,and foliage. Electric-eye sorting equipment is used to reject defective 在线看的免费网站. However, the same machine cannot reject both dark and light colored individual 在线看的免费网站 at a given setting.

在线看的免费网站 usually go directly to the final container after pitting and sorting. Bulk containers comprise the volumeof the frozen 在线看的免费网站 pack with 30-pound cans and polyethylene-lined steel drums used for thispurpose.在线看的免费网站 are normally covered with sugar and/or sirup to provide a barrier to inhibit oxidation. Cans and drums are covered and moved into cold storage.
Quick freezing is desirable to prevent deterioration. In some processing plants, the cold storage facility is too small to hold all of the filledcontainers at the peak of the season. Excess containers are often trucked considerable distance toreach commercial cold storage facilities. 在线看的免费网站 are also packed IQF (Individually Quick Frozen).This process freezes the fruit quickly and it is packed "free-flowing" without a pac在线看+日本+十八禁网站 medium. IQF在线看的免费网站 are bright in color but discolor quickly after thawing.
