If the budget and resources permit then below is the ideal method of sap collection for coconut and sugar palm.
A small house in center of 500 to 1,000 coconut plantation. Several large polyethylene hoses run through the farm. Then numerous smaller polyethylene hoses are connected to large ones. The hose end have wider tips to fit the coconut infloresence.
After cutting the coconut infloresence, a hose is fitted. The sap will flow continously from cut infloresence, to small hose, to larger hose then to a centralize collection chamber. Important pre-processing procedures maybe done here before transport to main processing area.
1) Less labor. Fit the hose to cut infloresence and the sap will flow continously to centralize collection tank.
2) May skipped or lessened the repeated trimming of cut infloresence. The enclosed system prevents stalk drying.
3) More yield. Longer stalk life span means longer collection period and more harvest.
4) Less contamination. Automated and eclosed system means less contamination. No dirt from air, leaves and other trees. No rain water infusion during rainy days.
5) More control. Harvest and process sap every hour for maximum sugar yield, for sugar and syrup production. Harvest twice or thrice a day for alcohol and vinegar production.
The same is true with sugar palm and nipa palm.
